After about six months with the Xlite V3 Medium, their first proper gaming mouse, they had no QC issues. It's solid with almost no creak, has minimal button travel, a crisp, well-stepped scroll wheel and a nice matte coating. The palm-grip shape is comfortable, though the bottom-left edge presses into their palm a little.
“The Xlite V3 is very stable and well built despite its weight (55g for medium size) and open bottom design”
