All the buyer read this. After getting this mouse just make a call to Dell Tech. Support i.e 18004250088 and give your D PPID No. Present behind your mouse and unique for every product. Then they will tell your mouse model no and whether its a genuine product of DELL or not. And do your product registration. So, in case if you are having any problem within 1Year then call to Dell Tech. Support and tell them your problem. DELL is providing the replacement instead of servicing. But, Keep your invoice ready. In my case its a genuine one and having 1year replacement warranty.
So, Go for it because within 7 Days If something goes wrong Amazon is there and after that DELL is there to replace your product.
Little smaller in size for big palms, not recommended for gaming users due to 1000 DPI. But for daily and normal users is the best one.
