I highly recommend A4Tech N70FX padless mouse for its durability and dependability. This mouse is just the right size for my small hands. It has been serving me for two years now and I use it everyday for more than 16 hours of online work. It has a double click button as well as two other extra buttons on the side which I use for zoom in and zoom out tasks. I don't know if it this mouse is still in production but I still see this being sold in A4Tech outlets and computer accessory shops. To date, this is my longest-serving mouse. If I will have to buy another one when this retires, it will still be the same model.
I bought A4Tech webcam 1 year ago it stopped working on my old computer, I tried it on my new computer, and now it's working. I use it as a microphone more than as a webcam. I've never used a mouse from A4Tech, but I think that A4Tech is a good company. Obviously their products are of good quality.
