Review on TeckNet Portable Wireless Receiver Adjustment by Fisseha Rodgers

I bought 2 of these in October 2014 and they seem to have upgraded the model a bit. I see a big difference, my old model only uses 1 AA battery, but the current model uses 2 AA batteries. This is a very inexpensive mouse that can handle anything and you'll even forget this thing is battery powered because I can't remember the last time I had to change a battery. I remember only replacing the battery once after purchase! The main reason for this mouse's ultra-long battery life is that it quickly goes to sleep when not in use. It feels like going to sleep after a few minutes of inactivity, which can be annoying at times since you sometimes wonder why the cursor isn't moving when you move your mouse. When this happens, it means your mouse is sleeping and you need to press the button to wake it up! Use this mouse on a desktop that I rarely use (because I have several laptops that I use more often) so I don't have to worry about frequent battery changes. Although there is an on/off switch at the bottom, I never turn it off because of its sleep function. It's also very comfortable to hold due to the contour shape and I prefer the USB receiver as my desktop doesn't have bluetooth but even if it did have bluetooth I prefer the 2.4GHz wireless connection via USB dongle because it more provides more reliable connection than Bluetooth. Highly recommended for its price. Hope this helped!
