Excellent mouse!
Style: Right-Handed, Pattern Name: Mouse, Color: Graphite
This is exactly what I was hoping it'd be! I was using a silent click Logitech mouse before this one and I was liking that aspect, but it was kinda small and was starting to cause me wrist pain. This mouse has helped alleviate that and still get to keep the quietness. The scroll wheel is also super cool. It's kinda fun to just spin sometimes haha. It feels well made and works great so far! No issues whatsoever!

Comfortable, but not well laid out and a bit too expensive.
Style: Right-Handed, Pattern Name: Combo, Color: Graphite
I have used a particular brand of keyboards for decades because of their features, comfort, reliability, and functionality. However, I type non-stop at my job and my employer usually just gives me run-of-the-mill equipment to use, so I always buy my own. My typing style will literally eat the keys off after about 2-3 years and 80% of the letters are gone off the keys in less than a year. I tried milking my last setup for an extra amount of time, but it was pretty bad. So I did some shopping for an ergo setup like this. I have a lot of nerve damage from my career choice so these features are important to me and after some shopping I landed on this selection. I will say I do like the feel of the keyboard and even though the mouse takes some adjustment I find it easy to use and very comfortable. So far the keys are holding up well to my abuse. I like the comfort of the wrist rest as well. The only real negatives are the following: I don't care much for the keyboard layout, the arrow keys are in a goofy spot, and the home end pg up and down keys are in a terrible place as well. It took forever for me to get used to the backspace and delete key locations too. I'm adjusting okay but it has not been super easy. Also, I don't like the position of the function keys to activate the other operations mapped to the F keys. Their selection for what these functions are is not for someone in business. It seems that it is for a teenager. An emoji key? Seriously? The media keys are pointless as there is no forward or back skip feature and it takes both hands to use them . You have to take your eyes of what you are doing and look at the keyboard just to use these features. The function and windows key should be switched in position as well. Being a PC and not a Mac person may be one of my issues because I don't like the labeling of "start/opt" A feature of this particular unit is sometimes helpful and sometimes not. It seems to have an overactive "enter" key function. Randomly, it hits enter without any input from me. Granted I have a lot of papers flying around but it can happen at inopportune moments, costing me extra keystrokes to undo what was done by this issue. Sometimes it is helpful but I prefer to be in control of what my keyboard is doing and not the other way around. I do like the action of the keys and the comfort, like I said more of my issues are related to specifically how I use it. I have not had any connection issues, battery issues, or any other technical issues. It appears to be fairly reliable and accurate. The last thing I would say is that this setup really seems overpriced. Not sure what that is about but if I had paid for it rather than my employer I would not consider it worth what I paid. With the pluses and minuses I would rate this as a decent purchase but not an ideal piece of equipment for my specific use.

High Quality and Operability - Great!
Great mouse! Not only good, but feels and operates as well as, or better than a Microsoft mouse, and a lot more reasonable! Comes with AAA batteries, the USB transceiver is stored inside the battery compartment (good when packing and traveling), and a white support strap lays down below the installed batteries so that it is easier to remove them when its time to change the battery. Be sure to go into Control Panel/Mouse and make any click-speed or mouse movement adjustments to your liking. I plan on buying another one of these for my second HP laptop. The USB transceiver is immediately responsive and you will see a red laser at the bottom of the mouse.

Works Perfect, No Installation Needed, Perfect Size, and Wonderful Price!
Several months ago when the keys on my laptop mouse pad started to go out, I was really irritated because I have gotten so used to using the mouse pad that I was worried that I wouldn't be able to work as efficiently using a wireless mouse. I knew that it would only be a few days before the keys got to the point that I wouldn't be able to use them and started looking on Amazon for a wireless mouse that I might possibly be able to stand using on a daily basis. I spotted the AmazonBasics Wireless Mouse and thought that it wouldn't be that great because it was way cheaper than most of the other wireless ones that I could find. I went ahead and placed my order because I needed something and thought that if it didn't work that well, I wouldn't be out of that much money. When it arrived, I was happy to see that it was a tad bit smaller than other ones that I have used with desktops in the past since I have small hands. I opened the package, popped in some batteries, plugged the nano receiver into my USB slot, and it was working instantly. I thought that it would take some time to install ( I did not read much on it when I purchased it honestly, I just needed one quick!), but was SO happy to see that it needed nothing to be installed. I have been using this wireless mouse for about a year and half now and I have recommended it to SO many people who were looking for one. I work at home on my laptop 7 days a week and anywhere between 12 - 18 hours a day. I only have to change the batteries about once every two months (sometimes it will go a little longer and sometimes a little bit less - not sure on why though). This mouse has worked flawlessly since the day of purchase and I was SO wrong to think that because it was cheaper than the others that it wouldn't work as well. There has never been a time where it disconnected from the computer or that there was any issue using it. A few times when it has needed the batteries changed and I wait a few days, there is a tiny lag - but that is all my fault. The AmazonBasics Wireless Mouse has a little red indicator light that lets you know when the batteries are getting low and need to be changed. I like that feature so that I'm always aware of when they need to be changed. Since I travel a lot, this mouse is great because it doesn't take up a lot of space in the laptop bag. I also never have to worry about losing the nano receiver because once you remove the little door to the battery area, there is actually a space that the nano receiver clicks into making it perfect for travel. If you are in the market for a great wireless mouse, I would recommend the AmazonBasics Wireless Mouse because it has been through over a year of my all day, everyday use and still works just like the day that I purchased it!

It works and is well priced.
This mouse works as well as much higher-priced brand-name items. It fits well in the hand. The durability is very good. Considering the price compared to other brand names, this is a very good value.
