To begin- I should state that I've been in the mouse community for a few years now and I've purchased mice from many different brands, big or relatively little. I've used Razer, Logitech, SteelSeries, Zowie, Corsair, Glorious, Pulsar, etc.I always seem to find myself coming back to either Razer or Logitech for specific needs that other brands don't necessarily offer.I have a lengthy history with Razer products, and that includes their Viper line of mice. I've owned the original, the mini, the ultimate edition, the 8khz wired release, as well as the Viper V2 Pro. There was one thing that kept my away from these mice for so long- shape.The original Viper mice, while excellent, weren't good for me comfort wise. The hump wasn't pronounced enough, and the curvature on the sides would cramp my hand every single time. I know, I know- why keep buying a mouse with a shape that makes you uncomfortable? Best answer: I like symmetrical mice, and other than shape, the Viper was/is amazing.Enter the V3 Hyperspeed!I was leaning towards 4.5 stars, but since I can't post a half star I'm comfortable rounding up. The V3 boasts a few changes that, in my personal opinion, are upgrades.The sides of the mouse are less aggressive with their curvature and I found them to be much more comfortable for my hands which are roughly 20x11. They've also done away with any worry of your ring finger clipping the side of your secondary click. They gave this mouse the same treatment the Deathadder V3 pro received.Weight isn't bad at all. It's around 82-83 grams with the included alkaline aa battery. I was able to get it down to a comfortable 70ish by using a lithium aaa and a separate aaa to aa conversion kit. This can be reduced even further by placing a small piece of aluminum foil between the battery(+) and the mouse's contact point.And another point to add- batteries. This mouse is NOT rechargeable, and it does NOT come with any included cables. For some this may be a deal breaker, but for me it's perfect. I don't mind rechargeable mice, but with 4K polling becoming the new " standard " I imagine constant charging could be a nuisance.However, there's a kit on here from PowerOwl that contains 8 aaa batteries and a charging system. I paid around $30 for the rechargeable lithiums and the aaa to aa converters in total. The converters came in a 10 pack so that was nice.This mouse is paired with my Hyperpolling dongle which can be purchased separately, or bundled together with this mouse when purchased from Razer.This. Thing. Is. Insane.When it comes to tracking accuracy I have absolutely nothing bad to say. The Focus Pro 30K in this mouse is the same sensor found in their flagships. Kudos to Razer for implementing that into their Hyperspeed line, which is widely recognized as their budget tier lineup.A few grievances of mine are that M2 ( right mouse click ) is considerably light. It might just be a case of heavy finger, but I found myself accidentally actuating the click at times.The side buttons are different in the fact that they are separated and have a bit of space between them. This is a good change, but I utilize M5 ( front side button ) as a Hypershift key, and it makes it a bit more difficult to hit M4 due to that split in distance. If you don't use Hypershift, then this should be of no concern.My copy has no creaking on the shell, no severe rattle, and the clicks are very crisp. I attribute that to the Gen 2 mechanical switches Razer are using in this mouse.For $70 you can't beat this, in my opinion! You're getting an insane amount of performance for a reasonable price. Pair this with a 4K polling dongle, grab some lithium rechargeable batteries, a few converters and you'll be fragging without the worry of cable drag in no time!Final score: 4.5/5Amazing job, Razer!
