I ordered this mouse from "UKMobile" and it came the next day, which i didn't expect at all. I ordered standard delivery, expecting it to come 5-6 business days later but i was pleasantly surprised too see that it had come the next morning. The mouse itself is a great size for gaming, easy to claw and palm grip. The dpi switcher is really useful when gaming and browsing the web.
The only downside to me is that when you take the mouse off the mouse mat, or any surface, the cursor stutters on the screen. It's understandable why it does it, but it's not ideal when you reach the end of your mouse mat while playing games.
Apart from that it's great, feels weighty, the buttons have a nice feel to them and the grips feel great.
