BATTERY NOT INCLUDED. Super easy "set-up." We'll see how it holds up. I'm not into gaming, so I can't address its usefulness for that purpose.

Mouse works great... exactly what I needed for my second office.

I use this for gaming. I have pretty small hands and this is maybe a bit small even for me but nothing too major. I know other reviewers have mixed feelings about the sleep feature but I personally like it since I don’t have to worry about accidentally bump clicking something when I come back to my desk. All around it’s a pretty solid mouse, works for me but definitely would look at other options if my hand was bigger.

Works great no problems at all

Best purchase. East to set up and use. Highly recommend it.

Love it. Got my wife one, she loves it. You too could love this moase (canadian pronunciation). Sleep mode is great... saves batteries.

I'm guessing that the reason really detailed written instructions are not included is that these units are sold in many different countries, and it would take a lot of paper and translation requirements. Still, I think it would be helpful to have a simple, but detailed step-by-step pictorial instruction for basic setup and functions. It's basically 1. plug the dongle into your computer, 2. put a battery into the mouse, 3. press down once on the top button to start up. One complaint I have is that the markings for the positive and negative battery terminals are very faint, so I mostly had to determine battery +/- terminal orientation by looking at which end of the battery slot had the spiral spring, which is conventionally the negative terminal. The manufacturer should re-tool the molding die for the battery housing component so that the positive and negative marking are much more prominent. I wonder how many of these get sent back simply because the buyer put the battery in with the wrong polarity, and didn't think to try reversing it. The product description doesn't say anything about reverse polarity protection being part of the design, so I don't know if reversing polarity fries the electronics permanently. As other buyers have mentioned, the automatic reversion to sleep mode does happen a bit sooner than I'd prefer, but overall it's still easy enough to just tap the top button to boot it up again, and it's nice not having to turn it upside down and turn a tiny little switch on or off to take it in or out of service.

The delivery was quick. The mouse seems to work great (first day using it). The directions were very easy to follow.

I just love this mouse, definitely my favorite of all time. I am in music and video production so I'm at my computer about 8 to 10 hours a day. This is definitely the most ergonomically comfortable mouse I've ever used. Terrific customer service as well. I had a problem with the scroll wheel not working properly after about a month. HOTWEEMS customer support responded to my inquiry right away and provided me with a new mouse. They were very attentive every step of the way. I highly recommend this mouse and this company.

As an artist and gamer, it's really important to have a good mouse, preferably wireless. This one is extremely well for use so far. I did have to turn the sensitivity down a good bit when first using it, but, otherwise it's been amazing.
