In my opinion, I think the Razer Viper V3 Pro is a little bigger, longer and it feels a little bit tall on its height it would be very uncomfortable. Sometimes i had a issue of the mouse slipping off my hands when im in the middle of the match. However, I do really love the Optical Switches,IPS,Dongle,Cable and the grip tape. They all looks cool and high quality to me but one thing that has change is the Viper V3 Pro Shape doesnt look similar to the rest of the  Viper which is a little disappointing. I hope the next Viper V4 Pro would look exact the same shape as the Viper Edition it would be very nice if this happen.
