Well I will say that the RAT is not that high quality but it will not break easily. In my case the wheel broke b.c I tossed it across my desk b/c you dam noobs made me rage rofl. The main reason I like it is that after over 2 years of ownership it is the first mouse I can use for hours and hours and hours at a time without any pain developing in my hand or wrist. All previous mice I have had required me to massage the side of my hand and or apply ice once a week to prevent permanent damage. So no matter how many small issues this mouse may have I would ideally like to fix it b/c I trust that it is good for my health.
