Sensei 300 and regretting it. The sensor isn't bad, but the shape is meh, and the build quality feels way inferior to most gaming mice from inferior companies, price at 10–20% of its price. And it already has occasional hiccups from time to time, forcing me to reconnect it from time to time. It'll take a while before I find one that's truly mine. And when I do, it may well end up being a lower model or an inferior brand compared to the great names of the gaming industry.
