The reason for the purchase of this mouse were my problems, cope with my little laptop mouse to come. She just was not compatible with my big hands. This lead to inaccuracies in the handling and to a cramped right hand. So I was looking for a larger mouse. You should have no special skills, but simply only work effectively and be cost-effective. So by Price Compare Logitech B110 was my favorite. They previously met my expectations fully. It is actually quite large. That may not be many a chic enough, but my health is important to me because. She fills my hand out completely, so that handling is very pleasant and relaxed. It glides well on all surfaces, the so happen on my desk (desk surface, blotter, paper, etc.). The keys respond reliably and with the "correct" pressure point. The wheel is easy to operate. The accuracy of the optical pickup, I am completely satisfied. Well a mouse is when you do not think of it when working with her. This is the case with this. Whether they will make their good qualities for a longer time to prove, of course you can not foresee. But the solid impression suggested by the at least.
