This is the only Bluetooth mouse with 5 buttons and is affordable. The mouse is good, hear good and has no latency. The only time I was a victim of latency, it was at the airport with 15 phone around. I am served on a laptop to play fps. The good surprise is that this mouse comes with a carrying box ... it's perfect, once you are more than necessary, the mice were stored in his box and that it remains protected once in a bag Backpack among many other things.
