I have been using this for about a month. Ergonomics is ok but not that great. Unless your hands are very big, you will find it a bit difficult to get to the no. 9 button on left side of the mouse.

great product, arrived on time

Very good mouse, high quality craftmanship. I have the BlackWidow mech. keyboard and I figured I'd give the Razer mice a try. I wasn't disappointed. Mouse is a good size for my larger hands and has a higher DPI that I'm used to (which is a good thing). My CS:Go game got better with this mouse..

Great mouse; good fit in hand; higher DPI

none that I've noticed so far

Looks and feels great, works well, while it lasts. 2 stars because it broke down after less than 2 years of use. Just came out of warranty, too. Not recommended at all, at this price.

Like other posters, the left click turned into a double click after about 3-4 months of light usage. I expect much more for a $70 mouse. I've read online that this is a common problem with a few models of Razer mice. Luckily I got the in-store product replace plan!

Feels very nice; easily adjustable sensitivity

Poor quality buttons

Had the button start double clicking at holding when i was only clicking once. Took the mouse apart and cleaned contacts with rubbing alcohol....Problem Solved!!!!

Love how big it is compared to most mice; It fits super comfortable and you dont have to drag your pinky on the ground; Cord is cool and braided; The laser is super accurate and quick; The option of the movable buttons is very nice as well

Braided cord is way too stiff; Which I believe is causing my cord to have poor connection and stop working sometimes; Had the button start double clicking at holding when i was only clicking once; Took the mouse apart and cleaned contacts with rubbing alcohol....Problem Solved!!!

I bought this mouse a few years ago, back when the DPI maxed out at 5600, and I can happily say that I don't regret the buy at all.

Amazing response; very sensitive; easy to use

Minor difficulty with left mouse button

Coming off a standard optical mouse, this issue is super. I can't think how precise the tracking is. The mouse arrow no longer jitters when moving slowly. The feel is superb, the wheel feels solid. If anything, the application does have a small finding out curve.

It's really comfortable, I don't actually like the ajustable side buttons but apart from that its great

Bought this mouse Twice and broke bothe times in a few weeks. HORRIBLE QUALITY and overpriced!!!
