I trackpad several weeks tested under Windows because I was curious obs could replace my mouse. I think the development of interesting and creative, the optics appealing. However, I can use it only an hour or less because at the latest stop working properly because sweat easily my fingers then. Far too vulnerable and not recommended for continuous use. Nor is it enough times just to wipe your fingers on the sweater I have to wash so that they are dry and grease-free. The keystroke is also too hard for my taste.
