Keyboards and mice · Razer
Owners keep it as their main gaming mouse for its light weight, easy tracking and well-liked coating, while some note it is still heavier than mice from smaller specialist brands.
Owners are divided on weight, but the positive side is specific: one owner credits the lighter weight and lighter click with making tracking effortless in Apex Legends, and another coming from a 96g Mamba Elite says it feels excellent in the hand.
Weight is also where the reservations sit, and owners are divided on it. One owner says weight is the only real knock against it, because smaller specialist brands make lighter mice, though they add that it still beats many big-brand mice.
The Razer Viper V4 Pro is a very light wireless gaming mouse. Razer doesn't sell a plain "Viper V4", so this page covers the V4 Pro. It is built for competitive PC players, especially people who grip the mouse with their fingertips or a claw grip.

From the maker's spec page, checked October 9, 2026. A blank row means the maker does not state it.
At 49 g it weighs about as much as a few AA batteries, so fast flicks take little effort. Up to 180 hours is the longest it lasts on one charge. Running at the top 8000 Hz rate drains the battery faster, so most people will charge it about once a week or two. DPI and polling rate only matter if you play fast games, and almost nobody needs the 50,000 DPI maximum.
Pick up to three. You get a page with just those, side by side, on the subjects owners raised.
For several owners it has become the mouse they reach for every day. One calls it among their favourite mice of the past three years, another moved to the Viper V4 Pro after other shapes never felt fully comfortable, and one rates Razer's soft-touch coating on it among the best they have used. Sensor performance comes up as a strength too, with one owner saying Razer's sensor work sets the standard other makers aim for.
Some things took adjusting to. One owner found the sensor felt floaty now and then, even at the lowest lift-off setting. Another, coming from the Viper V3, felt the clicks, the scroll-wheel actuation force and the coating had all moved away from what they like. Comfort accounts are mixed rather than negative: the owners who raised it treat shape as personal and suggest picking the mouse that holds most comfortably rather than looking for a perfect one. Razer's old Synapse software was a sore point, but one owner notes there is now a web-based option.
The owner who liked the newer clicks least still judged its overall build quality as pretty good. Nobody in these accounts reports a V4 failing outright.
One long-time Razer user describes creaking clicks and uneven left and right click force across roughly eight Razer mice over the years. That is about the brand's quality control in general rather than this model specifically. Long-term accounts of the Viper V4 itself are thin: these comments mostly cover first impressions and day-to-day feel, not how it holds up after a year or more of use.

Nothing with a clear majority yet. Owners who raised these subjects were split, or too few to judge.
Nothing has a clear majority against it yet. Counted from the owners who raised each subject, not from everyone. A subject is judged once at least 4 owners raise it.
13 more subjects came up from fewer than 4 owners each, which is not enough for a fair reading. To see how it stacks up, compare it with another machine.
The same owner, asked again at each point. Fills in as owners answer.
Two questions: how long you have had it, and anything you would like to say about it. Then we ask again as it ages. This helps our mission.

Before you buy one used, ask the seller: how old it is, whether it was ever repaired and by whom, and whether any of the parts above have been replaced. Ask to see it run. A receipt tells you the warranty start date; most makers honour the term only for the first owner.
