This mouse is basically the Prime with a extra sensor for LOD which might not be something you need. I personally prefer a higher LOD so the regular Prime performed just fine for me. What I like though is the extra screen on the bottom which you can use to customize the features and settings of the mouse so you don't need to go into Steelseries engine. For the rest of the review I'll paste what I said about the Prime - I have tried about 50~ gaming mice and so far this has been my favorite. Most importantly the shape is amazing the way its set up! Large ergo hump in the back, but thins out in the grip width quite nice. This mouse is usually on display at Best Buy so you can get a feel for it. The next thing i really like that I wasnt expecting are the main buttons despite being optical they feel very nice and tactile. I would easily recommend this mouse and the others from the Prime lineup. Heres my full list of pros and a few cons. Pros: -Shape -Buttons -Weight -Performance -Minimal design Cons: Stock feet and removable cable could be better

Clicks a smooth and feel great, glides are good, sensor is amazing takes some time to get use to the lift off distance sensor. 8/10

Fantastic mouse. It's my now everyday use mouse. It fits very well in my hand, the side buttons are a nice size. The main right and left click are the best feeling clicks I've ever experienced. They are extremely tactile and there is absolutely no mushiness whatsoever. Absolutely recommend to everyone out there.

It is a light mouse, which has good attachment and adaptation to the cloth, quick response, the material is not very convincing of its quality but I dropped it and it is still intact, I recommend it.

This mouse overall was pretty good and lasted me around 2 years. Eventually it did go out and I upgraded recently.
