Well crud. Sorry my response took so long. Yes, that's the one I was refering to. Quite honestly, I've banged mine around quite a bit, so I'd say durability is pretty good. Though, there is something loose inside the casing... I think it's a metal piece used for holding something in place. So, the curcuitry is fine, but it looks like one of the connectors is loose. It still works great, but I do try to make sure that connector isn't bothered to much (I don't want the wires to break loose. If it's what I think it is, that might be possible, though I'd say unlikely).
One other thing I forgot is that, occasionaly, it's unresponsive (it doesn't happen very often, which is why I forgot about it). This has never happened to me while ingame. But, sometimes when I start up Chankast (other emulators as well?), none of the buttons do anything. Unplugging the adapter from the USB port for a few seconds/minutes usually solves this problem, though a restart works everytime. This may be a concern for you. Personally, it's a mild annoyance. It's never really been a problem for me, but I thought you should know, incase you plan on buying one. Also, be sure to check out their site, and update your drivers. The drivers it comes with are a little old (I think).
Hopefully that information is helpful to you. Sorry it took me so long to get back to you on that. I've been offline for awhile. Mouser X over and out.
