SPC Gear GEM Plus @ TechPowerUp
 

Essentially, the ambidextrous SPC Gear GEM+ is a refresh of last year's LIX+. The same shape, but this time without holes, a still low weight of 67 g, new Kailh GM 8.0 switches for the main buttons, and PixArt's latest PAW3370 sensor—all for a highly competitive $44.99.
