**UPDATE** ***BUYER BEWARE*** Today I downloaded the recommended drivers from the Tecknet web site. After installing, the only thing that worked on my mouse or touchpad was cursor movement. Computer was unusable. Clicks were disabled. Reboot was pointless because the drivers are configured with autorun. Your computer is now a brick. The only way I fixed this was to go to the task manager (Ctrl-Alt-Del) Surprisingly the clicks did work. I disabled the service and went to "startup" and disabled the startup of the auto run mouse drivers. I am tech savy but if you dont feel like messing with this and spending lots of money and time with a PC repair tech, look for another manufacturer. I like plug and play... This is plug and pray... and a prayer wont help. This is a flawed product from start to finish.... Hardware AND software. I am really sorry I recommended this to anyone. And I did buy 4 of these devices. I am past my window of return so unless TECKNET WILL REFUND ALL OF MY MONEY, These will go where they all belong. In the trashcan....All 4 of them. I will remove this scathing review if I am OFFERED A REFUND for all 4 units. ***HERE IS MY ORIGINAL REVIEW*** Ive tested this mouse for many hours and weeks. Heres the truth. I bought 4 of these around December 2018. They ALL behave the same. I bought one for Dell XPS13, one for Surface Go, and one for a Samsung Tablet. One blue, one red, one grey and an extra grey one for backup because I "thought" there were a nice mouse... Time told the truth. First: Battery life is advertised as 24 month. This is a blatantly false claim. The above advertised copy says: "...up to 24 months on just 2 AAA battery! There is a handy indicator light to let you know when it is almost time to change the battery" blah blah blah. The truth is, this indicator starts to blink after 9-10 days (4 out of 4 devices). I am lucky to get 2 weeks out of each mouse before battery starts to cause mouse to "skip" around the screen and move the pointer as if a "ghost" were controlling the pointer, not me. Again, each device exhibits this characteristic. And for the record, I use Duracell Alkaline AAA batteries from Costco. I use batteries from the same batch/package for other things. I dont use off-brand batteries. Second: It feels cheap. At first I discounted this because the mouse worked well, but now after using these devices (every one) for almost 3 months, I certainly would not recommend this to anyone. If you want an inexpensive mouse (this one, any color) be prepared to buy a large pack of batteries from Costco or somewhere else. Had I known this in advance I would have gone with a Logitech mouse or other better quality mouse. I wont be sending these back because I am out of the return window. Its disappointing that it took a 3 month "burn in" on my part to truly get familiar with these devices. What really angers me is that companies make false claims that make suckers out of consumers. Take my experience, take my advice... Keep on looking for a name brand. Amazon is a mine field where you can really get nailed. READ THE REVIEWS. Make an educated choice. You get what you pay for.
