The Rival 600/650 gaming mouse from SteelSeries is an excellent mouse, but it's let down by poor adhesive on the sides that hold the finger grips in place. When the mouse is exposed to high levels of heat from the environment or sweaty hands, the adhesive starts to heat up and allow the grips to slide around, causing quite the mess. Luckily, SteelSeries is aware of the issue and can ship out replacement grips for you.
Should you have an issue with your Rival 600 or 650 mice where the adhesive isn't holding onto the grips well enough, you'll want to reach out to SteelSeries support and inquire about the replacement grips. We've been informed that even if your mouse is out of warranty, you may still be in luck for some assistance. The company will ship out replacement side panels.
If you don't fancy waiting around, you can go ahead and order said replacement side panels from SteelSeries directly. Once you have the replacement grips at hand, simply detach the existing pair from the Rival 600/650 and attach the new ones to the mouse. Job done.
Even with this adhesive issue, which SteelSeries appears to be aware of and working to eliminate from future mice, I can still wholeheartedly recommend the Rival 600 (or Rival 650 if you're more into wireless) as it's an incredible gaming pointer.
