Wireless Mouse, D-09 Computer Mouse USB Cordless Mice for Laptop, Ergo Grips, Lightspeed 5-Level 2400 DPI, 16 Months Battery, Portable for PC Mac Chromebook (Red, 1 Pack)

Arrived on time and inone piece. Added AAs and plugged into laptop. All worked without an issues. Third one purchased and all three run like a champ.

The media could not be loaded.  Love how it fits like a glove. Easy to use and set up. Purchased a mouse jiggler that pairs nicely. Have had it for a month now with the same batteries as long as you turn it off and on when not in use.

I am very satisfied with this mouse. It is extremely smooth on the mouse pad, and easy to use when moving the cursor icon around on the PC screen. It does what it says and gives me relief so that my wrist doesn't tense up or feel like carpal tunnel syndrome. It's ergonomic design is also very nice. The contours of the mouse provide a nice grip, especially on the side for the thumb. The only reason I did not give it 5 stars is because of it's size compared to my hand. The mouse is about medium sized, which is adequate to the size of my hand. But I think I would benefit better from a larger cpu mouse.The wheel in between the main trigger buttons is very comfortable. It feels like it it swede and soft. It makes it very easy & comfortable to quickly scroll though pages.I can't say one way or another about battery life, because I have only had it for about a week. But based on everything else I've experienced with the mouse, I think the description in the ad for this product is accurate and I believe it will last as long as it says.

There are no connectivity issues whatsoever with this wireless mouse. It moves smoothly and is very simple to turn on. It's really great that it only requires one AA battery unlike my prior mouse that required two AAA batteries that had to be changed frequently. Due to the way my old one used up batteries quickly, I was skeptical about this new mouse. However, I'm pleasantly surprised that it truly does preserve the battery! It will pay for itself within less than a year with the battery money I'm saving now. It fits my hand great and is much better quality than many that are priced much higher. I was impressed and ordered another one to have at my office. I would definitely recommend this mouse!

The supplier refunded my money and I am satisfied.I wanted a cheap wireless mouse and bought the wrong one. It is NOT ergonomic and has two unmarked buttons along the top edge where I put my thumb. While working it is almost impossible to avoid unintentionally pressing these buttons causing unintended operations. I have already ordered a replacement.

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.

great mouse for an inexpensive mouse. only complaint is that the mouse wheel eventually does wear out. the encoder wears out over time. only other complaint is that the mouse wheel is crowned instead of flat. a flat wheel is more comfortable for middle clicking. if you middle clock a LOT the curved mouse wheel edge gets annoying

I use this with my laptop for personal general purpose use. The ergonomic design works well with my hand. Battery life seems long, probably due to the sleep mode, but quickly cones to life when you first move it. Other nice features include adjusting the speed of the cursor movement. Finger tip going back 1 page and going forward 1 page is useful.
