The Drop ENTR is a decent TenKeyLess mechanical keyboard. It has an excellent build quality, with a solid aluminum case and plastic cover that exhibits minimal flex. It has bright, white backlighting with four brightness levels that you can control directly on the keyboard. The Halo True switches on our unit are quiet to type on and feel responsive, but your fingers might get tired due to the amount of force required to move a key. If you prefer linear switches, it's also available with Gateron Yellow linear switches. The ENTR keyboard is fairly comfortable to type on, although it lacks a wrist rest. Unfortunately, there's no companion software for customization, and you can't set macros to any of the keys.
