“My VV4Pro creaks on the right side when my hand relaxes and adds a little weight. I can trigger it to creak if I squeeze the shell in the center or front, too. Pretty lame”— eraserking on r/MouseReview
“I own both viper v4 pro and superstrike. I didnt notice any difference in terms of click performance except the click feeling on superstrike is quite nice.”— Linuxdr0ptips on r/MouseReview
“I can confirm the jitter thing but it also occurs at 4000hz, 2000hz, and rarely, at 1000hz. I wouldn't be surprised if it's due to how frame sync shows up when polled. I don't notice it when gaming though at all”— Disturbed2468 on r/MouseReview
