Compare GravaStar Mercury V75 Pro vs Razer Joro

Reviewers describe the sound as clacky and generally pleasing, with one noting it is louder and more direct while others call it clean or good sounding.

When reviewers comment on sound, they describe a quiet, deeper, lightly thocky tone rather than a clicky or sharp one.

Actuation and switch behavior are consistently portrayed as precise and responsive, with stable performance, accurate registration, and rapid actuation/deactivation noted across multiple reviews.

PCMag found the actuation feel consistent across the board, with crisp scissor-switch response rather than mushiness.

Brightness is strong where discussed, with reviewers calling the RGB bright and highlighting brightness controls in the web driver.

Brightness can be adjusted and is generally usable, but battery life drops sharply when the lighting is pushed high.

Battery life is heavily mode-dependent: reviewers praise long endurance with lighting off or reduced, but multiple reviews say RGB dramatically cuts runtime.

Build quality is one of the keyboard's strongest areas, repeatedly described as sturdy, heavy, well-built, high quality, and aluminum-based.

Build quality is a standout, with repeated praise for the premium finish, sturdy aluminum top plate, and minimal flex despite the thin chassis.

The included cable is a weak point in the one review that discusses it, because it is a plain rubber USB cable rather than a braided cable.

The included braided USB-C cable is consistently seen as a nice premium extra, though at least one review notes that it is short.

Compatibility is generally positive for keycaps, Windows/Mac use, and select magnetic switch replacements, though switch compatibility still requires checking supported TTC and Gateron models.

Cross-platform support is one of the Joro's strongest points, with repeated praise for Windows/macOS use and Mac-friendly legends or layout support.

Connectivity is limited because the keyboard is wired-only; reviewers treat the wired setup as functional but restrictive.

Reviews consistently highlight easy tri-device Bluetooth pairing plus wired USB-C use, making switching between devices one of the board's most dependable strengths.

Customization is broad, especially around actuation, rapid trigger, lighting, remapping, profiles, and Hall effect features through the web-based driver.

Synapse adds meaningful remapping and feature control, but some reviewers note missing remap coverage or software dependence for advanced functions.

The 75% layout saves space versus full-size boards by dropping the numpad and full navigation cluster while retaining arrows and useful keys.

The compact 75% design keeps core controls while saving desk space, which reviewers repeatedly frame as a major benefit.

Durability evidence is positive, with reviewers pointing to heavy-duty construction, high-quality materials, and long switch lifespan claims.

Reviewers report solid long-term sturdiness, with the slim chassis resisting flex and everyday travel stress well.

Switch replacement is easy where discussed, because the Hall effect switches are hot-swappable and do not require soldering.

Ergonomics are helped by adjustable feet or folding legs that change typing angle, though one reviewer found the feet visually unusual.

Ergonomics are the clearest weakness: the fixed low angle helps portability but repeatedly causes fatigue or discomfort for some users.

Extra gaming features are a major strength, with rapid trigger, SOCD/LKP, DKS, mod-tap, profile switching, and advanced Hall effect functions cited.

Gaming extras like Snap Tap, NKRO, and anti-ghosting are present, giving the Joro more gaming utility than most travel keyboards.

Frame rigidity is strong, with reviews emphasizing a heavy-duty aluminum or metal case, sturdy feel, and high-quality construction.

Structural rigidity is excellent, with multiple reviewers explicitly calling out the lack of flex even under pressure.

Gaming performance is consistently rated highly, with reviewers reporting smooth play, strong FPS performance, no obvious performance complaints, and fast response.

Gaming performance is acceptable for casual or secondary use, but reviewers regularly stop short of recommending it as a primary board for serious competitive play.

Hot-swap support is clearly present where reviewed, letting users swap compatible magnetic switches without soldering.

Keycap quality is mixed: several reviews praise the PBT/PC materials and durability, while Tom's Guide strongly disliked the rough paint-like texture.

Keycaps get mixed-positive feedback: legends and shine-through are appreciated, but some reviewers mention smoothness or smudge-prone surfaces.

Key responsiveness is a major strength, with reviewers describing instant key presses, feather-touch activation, ultra-fast response, and rapid registration.

Responsiveness is decent overall, but reviewers disagree more here than elsewhere, with some calling it responsive and others saying the keys rebound too slowly.

Key spacing and navigation are mostly positive, with reviewers finding arrows and extra keys easy to locate and useful in the 75% layout.

Key spacing is generally praised for preserving full-size arrows and usable spacing, though the compact layout still takes some adjustment.

Key stability is directly praised in one review, which notes stable switches with minimal wiggle or wobble.

Where specifically discussed, the keys are described as wobble-free and stable rather than mushy or loose.

Latency performance is strong across gaming-focused reviews, with several noting no lag, low latency, or very fast measured results.

Bluetooth latency is a recurring caveat: several reviews say it is fine for everyday use and casual play but noticeable in faster competitive gaming.

Layout options are solid around the 75% form factor, variants, and configurations, though users wanting larger boards or numpads may still be limited.

The 75% layout with function row and extra navigation is practical, though not every reviewer loves the specific key choices.

Legend visibility is positive where discussed, with one reviewer noting the large themed legends remain very legible.

Main legends are usually praised as crisp and durable, but some reviews note that secondary functions are harder to see because they are not backlit.

Macro customization is mixed: one review says the web software can record macros, while another found no macro recording function at the time of testing.

Macro support exists and can be powerful, but some reviewers note that advanced macro-style features rely on Synapse being active.

Materials quality is high, with repeated references to aluminum alloy, metal, full aluminum case construction, and sturdy high-quality materials.

Material quality is repeatedly described as premium for the category, especially the aluminum top and overall finish.

Media controls are present through a volume knob or lever, including mute behavior, though it is not always a traditional rolling knob.

Media controls are available through function layers rather than dedicated keys, which makes them useful but not especially elegant.

Noise level leans clacky and noticeable rather than silent, but reviewers generally describe the sound as acceptable or good rather than harsh.

Noise levels are consistently low, making the Joro one of the quieter boards in its class and easy to use in shared spaces.

Onboard profile support is only lightly evidenced, with one review mentioning onboard presets and profiles.

The keyboard supports saving changes on the board itself, which helps retain profiles and custom behavior without constant software reliance.

Lighting control is strong, with per-key RGB, backlighting, side lighting, and lighting controls noted across reviews.

Per-key lighting control is a clear limitation: multiple reviews explicitly describe the lighting as single-zone or one-color rather than individually addressable.

Polling rate is a high-spec strength, with multiple reviews citing or testing 8,000Hz polling, though one reviewer considered it more marketing than noticeable.

Wired mode's 1,000Hz polling is a meaningful plus for gaming-minded users, even if the wireless story is less impressive.

Portability is a weakness because the board is heavy, wired-only, and visually or physically bulky despite its 75% layout.

Portability is the Joro's defining strength, with nearly every reviewer praising how slim, light, and bag-friendly it is.

Profile management is supported through presets and easy profile switching, though some layer behavior was described as limited or imperfect.

Profile handling is solid, with reviewers noting multiple savable profiles and the ability to switch between them later.

Rapid trigger support is a core strength, appearing repeatedly with fine adjustment ranges and advanced Hall effect behavior.

Reliability is generally positive where discussed, with the keyboard feeling durable and a reviewer reporting no major issues, though minor double-clicking was noted as fixable.

Day-to-day reliability is generally good once connected, but sleep behavior and the occasional reconnect hiccup keep it from being flawless.

RGB customization is extensive, with web software controls for lighting effects, colors, brightness, side lighting, and custom lighting behavior.

RGB customization is flexible enough for effects and color changes, especially through Synapse, but it is not as granular as Razer's full gaming boards.

RGB lighting quality is a standout feature, with praise for underglow, side lighting, bright effects, leg lighting, and the visual glow through translucent keycaps.

The RGB itself is widely praised as bright, vibrant, and attractive, especially considering the keyboard's travel-focused design.

The 75% form factor is generally practical, balancing desk space and function keys, but some users may prefer smaller travel boards or larger layouts.

The ultra-low-profile 75% form factor balances compactness with more usable keys than many travel boards.

Software quality is mostly positive because the web driver is easy and feature-rich, but some reviews mention early quirks, language issues, or missing macro support.

Synapse is usually seen as useful and capable, especially with Mac support added, but some reviews flag setup gaps or dependence for advanced features.

Sound dampening is well supported by foam layers, dampening pads, and case design that reviewers connect to a cleaner clacky sound.

Sound dampening is not a strength; at least one review specifically calls out a harsher landing and missing dampening.

Stabilizers are positively described in the reviews that mention them, with reduced rattling/pinging and good stabilizer sound.

When key wobble is discussed, reviewers describe the typing action as controlled and free of mush, suggesting solid stabilization for the format.

Switch feel is generally praised as light, smooth, stable, and pleasant, though switch choice is limited to linear Hall effect options.

Switch feel gets mixed-positive marks: the scissor switches are often called crisp, tactile, or satisfying for the type, but they do not replace a good mechanical board.

Switch options are limited, especially for stock switch choice and for users who want tactile or clicky switches rather than linear magnetic switches.

Reviews only discuss a single low-profile scissor-switch implementation, so switch variety appears limited.

Typing comfort is decent to good: reviewers liked the light switches and daily-use feel, though some disliked keycap texture or sensitivity settings.

Typing comfort is good for many users once acclimated, but comfort over very long sessions is less consistent because of the flat angle.

Typing feel is generally good or smooth, helped by light switches and sound tuning, but not every reviewer considered it great due to keycap texture or sensitivity.

Typing feel is one of the more successful parts of the Joro, with several reviews comparing it favorably to premium laptop keyboards or the Magic Keyboard.

Value for money is divisive: several reviewers find the premium build and design worth it, while Tom's Guide and another reviewer argue cheaper competitors offer better value.

Value is the biggest sticking point: reviewers often like the design and portability but still argue the asking price is hard to justify.

Volume control is useful and repeatedly noted, using a knob or lever that can adjust volume and often mute.

Volume control exists on the function layer, but the lack of dedicated controls makes it less convenient than on larger boards.

Wireless performance is a clear weakness because the keyboard has no Bluetooth or 2.4GHz wireless mode and is wired-only.

Wireless performance is good enough for productivity and casual use, with generally reliable Bluetooth pairing, but sleep wake delays and gaming limits show its ceiling.
