I have bought five mice from them, finally tired of the grips failing after a year, and dropping 120$ on a mouse that I hoped would be better... The feet started to run away again, the glue just disappointing. Steel series customer support made sure I knew they pronouns, but can't give me 15$ worth of grips even though I have 5 of their products. The tech support closed my ticket and they think I'm done writing bad reviews. They are $#*!ing dreaming because I have nothing better to do today.
