Great build quality, light weight
Summary: good value, premium feelings, light weightI previously used a CoolerMaster MM710 which is slightly lighter (-5g) and smaller in size. If you have small or medium hands you won’t be able to fingertip grip this Razer mouse.This Razer mouse has much better build quality than my MM710, there are no creaks when you pinch it on the sides.The 8K polling rate is not something I use, some people say it’s a good improvement over 1K Hz but I can’t really notice it too much playing CS2. The big downside is that when moving the mouse fast it uses up to 20% more of my CPU compared to 1K.The point where the cable attaches to the mouse is angle upwards so the cable won’t drag. The cable is very light and flexible so is not a hindrance.The surface is a smooth matte coating which is neither good or bad.The feet are very smooth and thick enough to have plenty of life in.The button clicks are not very loud and the scroll wheel is smooth but well defined. It doesn’t make an unpleasant sound.I would definitely recommend this mouse.

Solid Mouse with Great Wireless Features, But We’ll See on Durability
The Razer DeathAdder V3 is a really solid mouse, especially for FPS and general gaming. The Razer HyperSpeed wireless is nice as im able to use one dongle for all my Razer wireless device. Plus, the USB-C charging is awesome since everything I own mostly charges the same way.However, one downside Iâve noticed is the battery lifeâit seems a bit shorter than I expected. I find myself charging the DeathAdder V3 a bit more often compared to my other Razer wireless peripherals, which is a bit of a letdown.Overall, though, the mouse is fantastic in terms of comfort, performance, and precision, but the battery life could use some improvement. Still, itâs definitely one of the best mice Iâve used!

Good Mouse for its Price
Decent wired mouse, its pretty big for my hand but I was using an office mouse previously. The two mouse buttons are nice and clicky, there are two side buttons that are decent and programmable. All of the buttons are rated to go up to 10 million clicks so they should last a while. The scroll wheel is solid and has good grip. The mouse has mouse skates on the bottom, allowing it to slide better than without it. It comes with a decent sized cable, around 1.8 meters long. The mouse does feel much cheaper than any other Razer products I’ve tried but it is £20, so that’s understandable. It comes with a Razer Synapse install which allows you to change the mouse’s default DPI (6400) and lets you choose the lighting from the mouse to static or breathing, there are no other options. The mouse has a polling rate of 1000hz meaning it updates its position 1000 times per second, which is good for its price. In conclusion, its a pretty good mouse, especially for its low price.

Love it
Love this more than I thought I would, had like 3 death adder essentials previously and it was usually the scroll wheel or the double clicking that broke them. I have been using this a whole year (on the 14th) still acts brand new with no issues and I am surprised at its responsiveness considering its a wireless mouse, only need to put it on charge when I go to sleep every few nights, found out I actually prefer the lightness and no dragging from wires.Would highly recommend trying it if you aren’t sure about wireless delay or a lightweight mouse and you will be as surprised as me.

Great mouse
Probably one of the best mice you can get on the market. I’ll update this review if there are any flaws/damages over time, but so far it has been great. Handling the mouse feels smooth and very responsive. The mouse works both wired and wirelessly with great performance, and lasts a long time. The material of the mouse also feels a lot better compared to my old V2 Deathadder and I have not noticed any grime or dirt accumulating on the mouse over the last 2 weeks of frequent use.My only nitpicks are that there are no LEDs or special features on the mouse besides from the 2 extra buttons which makes it feel a little plain. The mouse comes with customisable stickers and grip pads for the mouse, but they feel like a cheap addition for a £104 mouse and I have not bothered to use them.

Amazing
Honestly perfect – never been so happy with an order. The mouse is really comfortable and looks insanely cool. I haven’t had any problems with it and it makes my gaming experience ten times better. It feels really responsive and fits in my hand perfectly. I have been looking for an affordable gaming mouse for a while and this one checks every box. I definitely recommend this if you’re looking for a gaming mouse.

The best gaming mouse out there
Iâve been using gaming mice for years, but nothing quite compares to the Razer DeathAdder V3 Pro. As someone who plays a lot of competitive FPS games, Iâve always been on the lookout for a mouse that offers precision, speed, and comfort, and this mouse delivers on all fronts.

Great feeling.Handels amazingly good, and light weight.The 8k pulling rate + the cable ver = lower delayThe only downside to using a pulling rate higher than 1k is that it demands cpu power, so if u have a budget cpu or an old one i wouldnt buy it for the higher pulling rate .But if u want low input delay + preformance i would put it on 2k pulling rate + 1600 dpi ( at least) so u can max-out the pulling rate and have a more stable pref/connection if u got the wireless one.
