Excellent product with even better aftersales,
This review is from: TeckNet 2400DPI Bluetooth Wireless Mouse, 24 Month Battery Life With Battery Indicator, 2400/1500/1000dPi (Electronics)
I have bought 2 of these - one for my main computer in the office and one for my laptop. Both have worked very well indeed - responsive and accurate.
One of them suddenly stopped working which I reported and it was quickly replaced with no quibbles whatsoever.
