The Roccat Kain 200 AIMO is one of the best affordable wireless mice available. With its 16,000 DPI sensor and brilliant build quality, you can't go wrong.
Fantastically comfortable to use with rubber coating; PixArt PMW3335 sensor works an absolute treat; 35 hour battery life with full backlighting isn't to be sniffed at;
Roccat Swarm is a pain to install; No compartment to store the wireless dongle;
