Our Take

Best for: Gamers and typists wanting a compact, customizable wireless mechanical keyboard on a budget.

The LTC Nimbleback NB831 is a surprisingly capable mechanical keyboard at this price point. Its 75% layout saves desk space without sacrificing navigational keys, and the hot-swappable PCB lets you swap switches to your preference. The volume knob is a nice touch for quick audio adjustment, and the dual-layer foam keeps typing from being too hollow or pingy. 4GHz wireless, and USB-C wired options. Battery life hits about 12 hours with RGB on, which is average for a wireless board, but can stretch to 80 hours with lights off. The included PBT keycaps are a step up from ABS in durability. 99, it's hard to beat this feature set. The main tradeoffs are the shorter RGB battery life and lack of dedicated media keys, but the volume knob and software remapping help. If you're after an affordable, customizable compact mechanical keyboard, this is a no-brainer.

Price Analysis

At $34.99 after a 42% discount from the $59.99 list price, this is an exceptional value. Mechanical keyboards with hot-swap and wireless features typically cost much more. This price is near the all-time low for a board of this spec, making it a great buy now.
