SANNOXY 2.4G Wireless Optical Mouse with USB Receiver - Cordless Computer Mouse for Laptop, PC, Mac - Ergonomic Design for Office Work, Gaming & Home Use

Got this item on April 26, 2014. Yes, 2014. I've had it for over a year and it's been working perfect! At $4, I was skeptical about buying this, as it was so cheap that it was probably going to break easily. However, the reviews were positive, so I gave it a shot and bought two.When I got it after almost a month (takes so long to ship since it's from China >_<), it came in a small plastic bag. I was like, "Okay, nice protection they got here. Bet it's damaged already." Surprisingly, it wasn't. I plugged it in and BAM. It worked. I played around with it a bit. It was light so I figured I could bring it around easily. The USB was small and convenient and there was a little plug on the bottom of the mouse that held it together. The sensitivity is great, but I found after a while that the middle click can sometimes take a few tries. Also, batteries must be replaced monthly or something, be prepared with a stock of them or else just buy two rechargeable batteries: one to use and the other one to use when the first one dies and is charging. Other than that, I was so happy with my mouse and couldn't believe it was real! I'm clumsy, so I've dropped it countless times over the past year, and it was still fine!The only problem I had was when my mouse started to gain and lose sensitivity quickly at random moments. It turned out that my battery was getting kind of soft, so I just replaced it and it worked!I'm writing this review on May 1, 2015. After over a year, my mouse finally broke. My right click button was damaged after I dropped it for the millionth time. This mouse, this cheap $4 mouse (plus battery prices and electricity bills from charging my mouse), after countless drops, finally stopped working. If you're more careful than I am (and this should be a lot of you), this mouse can last you a couple of years, maybe longer! I would recommend this to anyone I met with (if they're fine with 1 month shipping lol).
