I've had my gamepad for about one year and a half now, and it never failed, ever!
Battery consumption is great, I use mine about 4 or 5 hours a day, with vibration activated and lasts about 5 or 6 weeks between recharging. I've used rechargeable batteries for it (NOTE: not included with gamepad), only charged like 11 or 12 times in these two years.
Used with all kinds of games and applications, even i use it to control Windows Media Player or other multimedia apps.
Wireless range its amazing, and antenna can be kept hidden inside computer case, really nice.
Dropped it once and connection got reset, after a few seconds, I was back in action. Never failed again. Just been dropped about 3 times from hip height.
Highly recommended!
In picture, my gamepad:
I replaced the 1, 2, 3 & 4 buttons with engraved buttons from a Logitech Precision Gamepad, looks better I think.
