Awesome quality mouse
Fantastic value. First it feels like a quality mouse and works like a mouse 3-4x the price. It is solid and has nice weight to it, not like some of the flimsy competitors. I am buying another just to have.

Great Mouse
I normally use the Logitech M325c. I've gone through dozens over the years. It works very well, but they seem to wear out fast; the wheel scroll is what fails. I decided to give the Amazon Basics a try. So far, it looks, feels, and functions the same as the Ltech; it doesn't have the fun colors, but if it holds up longer than a year, it's a fair tradeoff. I will revise this review if things change in the future, but as of now, I would recommend the Amazon Basics and will replace the other Ltech's when the time comes.

Insanely good gaming mouse!
This mouse exceeded my expectations in every way. The first thing I noticed was how ridiculously light it feels β it glides so smoothly that aiming in FPS games instantly felt faster and more precise. The wireless connection is flawless with zero lag, and the clicks feel super satisfying and responsive.
Battery life has been excellent, USB-C charging is convenient, and the white design looks incredibly clean on my setup. I also love how customizable everything is without feeling overly complicated. Logitech absolutely nailed the balance between performance, comfort, and aesthetics with this one. Easily one of the best gaming mice Iβve used.

huge difference during long gaming sessions
The Logitech PRO X2 SUPERSTRIKE is easily one of the best gaming mice Iβve used. The first thing you notice is how incredibly lightweight it isβit glides effortlessly, which makes a huge difference during long gaming sessions. The responsiveness is top-tier, and the Lightspeed wireless connection feels just as fast and reliable as a wired mouse.
The build quality is excellent, with a clean, minimalist design that looks great on any setup. The clicks feel crisp and precise, and the customizable haptics add a nice touch for those who want to fine-tune their experience. Battery life is also impressive, and the USB-C charging is a welcome upgrade.

Best haptic-inductive trigger wireless lightspeed gaming mouse ever!
I'm so impressed that click latency and feedback feels much faster than traditional mechanical switches. Yes, you can tweak it via Logitech G Hub to adjust rapid trigger, haptic click, and trigger latency. As soon as I set to 0 for haptic click, it feels noticeably faster and I can CPS (Clicks Per Second) much faster nowadays, especially in Counter-Strike 2, and other competitive multiplayer game. In addition, mouse weight is 61g which still feels light, not hefty. Durability and material feels high-quality, not too mush, no rattles, no problem whatsoever. However, it comes to pricing, yes it is unfortunately expensive at a price of $179.99 USD, but hey, you pay what you get for value and performance. All in all, this is such a huge game changer and this is definitely going to change the meta when it comes to gaming tournament e-sport!
P.S. This mouse also supports Powerplay which you will need the Powerplay mat as well as the Powerplay coin in order to charge your mouse indefinitely. It also supports 8Khz polling rate and very high dpi resolution 44k+. I also wish Logitech would release G Pro X2 Superstrike 2C (smaller & compact version) in order to keep the weight down as much as possible (possibly 51g or less).
