Two numbers explain the Viper V4 Pro: 49 grams and 180 hours. Ultra-light mice usually force a choice between a small battery that keeps the shell light and a bigger one that keeps you playing, and Razer skipped that trade entirely. It is the lightest flagship-class mouse in this group and holds the longest battery rating at 1,000 Hz, and that combination is why it is the pick we hand to most people. Picking it up after a heavier mouse feels wrong for about an hour, and then everything else feels slow.
The shape is symmetrical with a gentle hump, flat sides, and no thumb shelf, which suits claw and fingertip grips and either hand. Underneath, the Focus Pro 50K sensor is rated to 930 IPS and 90 G — headroom no wrist can use — but what we cared about is that it tracks cleanly at 800 and 1,600 DPI, where most competitive players actually sit. There is also a sensitivity matcher in the software for copying your settings off another mouse, which saves a week of feeling off-target.
The durability story is what separates it from the cheaper picks. Both the main switches and the scroll wheel are optical, so there is no mechanical contact to wear into a double-click and no encoder to start scrolling backwards. Those two failures retire more gaming mice than anything else, and this design removes both. At 8,000 Hz the battery drops from 180 hours to about 45, so the headline figure assumes 1,000 Hz — a fair assumption, since 8K is a nicety for most players rather than a necessity.
Two things are worth checking before you order. The first is macOS: Razer lists Mac desktops and laptops as compatible, and it is the one place where an otherwise clean record frays, so buy somewhere with a return window if that is your setup. The second is the receiver — the high polling rate runs through the HyperPolling dongle, and a rear port or the bundled extension keeps it stable. Get those two right and there is very little left to think about.
Pros
- 49 g without a battery penalty
- Optical switches and optical scroll wheel
- Symmetrical shape suits most grips
- True 8,000 Hz wireless in the box
Cons

The lightest flagship-class mouse here, and the only one that pairs 49 grams with a 180-hour battery — our pick for fast, competitive play.
