Pros & Cons

Pros

✓ TFT smart display shows battery, connection, and Win/Mac status, plus custom GIFs
✓ Programmable knob controls media, RGB lighting, and mode switching on the fly
✓ Tri-mode connectivity: 2.4GHz, Bluetooth 5.1, and USB-C wired
✓ Hot-swap PCB fits 3- and 5-pin switches (Cherry, Gateron, Kailh, Akko), no soldering
✓ Triple-layer foam dampening (EVA, IXPE, case) for a thocky sound signature

Cons

✗ 75% layout drops the dedicated numpad and some nav keys
✗ Ships with linear switches only; tactile/clicky fans must hot-swap
✗ Bluetooth 5.1, not the lower-latency 5.3 on some newer boards
✗ Gasket mount and PBT caps, but knob/OLED add points of failure

SpecPicks Verdict

SpecPicks scored COSTOM Womier M87 75% Mechanical Keyboard Tri-Mode using a rating × review-volume × price-fit model applied to published specs and reviews across the gaming peripherals category. COSTOM's gaming peripherals lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for gaming peripherals of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.
