I love the keyboard with rounded keys allow fast typing and smoothly. It is particularly suitable for people with small hands. I am more reserved on the mouse, but this is only my opinion: in the beginning, it is very hard and therefore use requires several days of run, which is not the major problem. The trouble is that it seems disproportionate to the keyboard because, firstly, it is more suitable for large hands and, on the other hand, is struggling not to get out the Cursor field when we have a (great) ergonomic carpet ... Nevertheless, the bulk purchase of these two articles is far from a bad idea!
