I have huge hands and play with a conventional keyboard is quite clenching for me. This keyboard allows gamer myself comfortable use very successful, and all buttons are easily accessible to me. My wrist and my hand rests on the designated places and it is very relaxing. My back is also found in most law. Of course it took me a few days to adapt to forget the automation of conventional keyboard but the end result is very positive once the different optimized settings. The Synapse configuration utility is very well done and quite quick to customize. The ability to choose up to 8 "mapping" fast keyboard is just huge. In the end we end up with no less than 176 programmable keys! The plastics used are of good quality and the object is the most beautiful effect. The responsiveness of the keys is perfect. The only fault I can find him is the absence of a braided cable. I question the usefulness of the piece of spiral sheath placed over the cable. In short a detail. I rarely put 5 stars to a product but despite its price, well-being that gives me is considerable.
