Review on 🖱️ TECKNET Classic 2.4G Portable Optical Wireless Mouse: USB Nano Receiver, 6 Buttons, 30 Months Battery Life, 4800 DPI, 6 Adjustment Levels (Blue) by Helen Cheb

Inside is a mouse, an instruction manual and a piece of paper to increase the warranty time. By default, it is 1.5 years, but if you register a mouse on the Tecknet website, they will add another 6 months. The piece of paper also promised that the company would send free (!) samples of new products to those who would write good reviews on them. However, I'm afraid that not only will they not fit me for this text, but they will also deprive me of a guarantee.
