Review on 🖱️ TECKNET Rechargeable Wireless Vertical Ergonomic Optical Mouse - 2.4G with USB Nano Receiver, 800/1200/1600/2000/2400DPI, 5 Buttons - for Laptop, MacBook, PC, Windows, OS System (Black) by Carta Gutierrez

Very nice mouse. 1) Ease of use: It no longer hurts to put my hand on the mouse because my hand is in a natural position. 2) The lithium battery is a plus - no need to change batteries again. The battery has a decent capacity. My first charge lasted 45 days. I'm a software developer and I use the computer about 10 hours a day, so 45 days of use between charges is much longer than I expected and also longer than the manufacturer says (30 days). A suggestion to the designer/manufacturer: the LED should be on the left side of the mouse, not the right side. This product is right-handed, so it is usually placed on the right side of the table. When the batter runs out, the red indicator light is invisible. This can affect battery life as you may forget to charge it before it stops working. My suggestion to equal customers: Don't forget to charge your mouse every 2 weeks (the lithium-ion battery has no memory effect).
