A DEXP mouse (a $300 replica of this mouse) was once in my possession. She had dangling side buttons, a sensitivity switch button that didn't work at first, and a dead wheel after about six months. She had a few advantages, though, including a pleasant form and a rug sensor that worked like a charm. As a result, I sought out a similarly shaped mouse when searching for a replacement. There was no question in my mind that I had to steal this mouse the moment I laid eyes on it. Comparable to my previous mouse in every way, this new one cost only $8 and came from a "good" brand. However, it was discovered that DEXP is actually the same mouse, but with different stickers. The same shoals as DEXP emerged, but sooner. The quality is quite low, so please don't.
