For transparency this is my first razer mouse, and only my 3rd mouse. fist was a cheap havit mouse that came with a bundle. second was a steelseries 600. Honestly I assumed I'd get this mouse and be underwhelmed.
so far, it's been about 2 weeks. this mouse is ultra light to me coming from a steelseries rival 600. the steelseries was slightly over 100 grams so it's almost 30 gram difference. this weighing in at 74. I didn't really expect it to affect my or even be noticeable. boy was I wrong. instantly lighter and the feet on this mouse glide so smoothly.
very responsive and quick. thought I may have to turn down my dpi or sens due to how much lighter and smoother the razer is. However, from that heavier steelseries with weaker glide, to this much lighter exponentially better gliding 8k, it was seamless. adjusted extremely quickly.
The shape is great feels great in my hand. did take me a minute to get used to as far as that goes simply because my last mouse was bulky and an unorthodox shape compared to most gaming mice. Now due to that there was some weird stress, and fatigue that presented in my forearm. again it adjusted quickly. after, at max, a couple 3-4 hour sessions it was gone. There are 4 total side buttons, but theres a caveat there I'll touch on later.
the wire on this is absolutely perfect. 0 drag, dont even notice it's there until I look down. dont have to use my cord bungee either. I almost got the viper ult but knowing how this mouse feels, it would've been a waste of money to me.
As great as this mouse is there are a couple trade offs and things I didnt know. these are not in number of importance.
1) since this is ambidextrous, theres 4 total side buttons, one set on each side. Coming from a mouse with 3 side buttons and the way I had things mapped, I assumed I would be able to map all 4 buttons. wrong. the buttons are M4/M5 on each side. you have to choose if you are right or left handed in the app and that sets which side is being used and how they're numbered. kind of a bummer here but this is a personal issue not necessarily reflective of razer. coming from more to less is situational. I would just like that extra personalization.
2) The 8k polling rate. this provides an extremely smooth mouse movement. this may be different from person to person. maybe mouse pads make a huge difference I have a relatively cheap one atm. One issue I've run into is Apex legends WILL NOT run a polling rate over 2000 on a 144 hz monitor. or at least not on mine. rainbow six siege I can crank to 8k and no issues. so maybe its game/display/system dependent I dont have a way to test it.
3) I'm a person who enjoys rgb and wish there was more. this is a non issue for most I'm sure, but this is about the only thing the steelseries had over this mouse was the customization options for rgb.
4) the liftoff distance. this is the number one win for steelseries. they had a liftoff distance as low as .5 mm lift off distance which I absolutely loved. the lowest for this mouse is 2 mm. so lifting and lowering there is mouse jottering I'm not a fan of but overall not a big issue. big win for steelseries here.
Barring any huge issues this is a mouse I would 100 percent recommend at time of this review. buy it, check it out. I doubt you'll be disappointed!

I like it
Good, albeit with some issues. The cable is very stiff and as a result the kinks from packaging are permanent. The shape is not for me (too long and not high enough of a hump to cup with my hand). But 8KHz polling is amazing and the difference in game was instantly noticeable for me. I immediately noticed how much less effort I had to put into aiming to achieve similar results as my old mouse (albeit the shape is worse). The thumb buttons on the other side of the mouse do not interfere with my grip but I did disable them to prevent any accidental clicks. I also noticed a latency difference with the optical switches over my previous mouse. Click timing became a lot easier.I haven't experienced any issues in any games that I play. The people complaining about issues are probably running underpowered computers with too much bloat running in the background. The Razer software should be installed on another PC or in a burner OS install. It's unbelievably bloated and is borderline malware.The firmware this mouse ships with is extremely buggy and should be updated. It has issues such as having to replug it on every cold boot to get it to work and the LOD adjustment not working. Once updated, these are fixed.I bought and reviewed this as a $40 mouse, which is a good price for this mouse. Anything higher might not be worth it due to the issues I listed.

Es muy ligero, su peso es casi imperceptible, su manejo es notablemente mejor que cualquier otro raton que eh tenido.
Como todo lo razer, viene en su elegante caja con calcomanías, su bolso de tela e instructivo.
Completamente recomendable este producto.
***El unico detalle es que el repartidor no comunicó su llegada,lo avento a la puerta y se fue sin avisar, lo cual es desagradable ya que puede dañarse o en mi caso que tengo perros, ellos pudieron dañarlo. Únicamente por que estuve pendiente de la pagina fue que supe que el paquete llegó. Seguramente fue un repartidor externo y eso habla muy mal de Amazon... En fin.
actualizacion: luego de 6 meses, esta porqueria ya no funciona nada bien, la rueda al bajar sube y al subir baja
