I've got the same controller, and I haven't had any problems with it, I've also got a 2.4ghz cordless phone in the same room, and the base is right next to my wireless router (also 2.4ghz). The first couple times I used it I had to manually force it to link with the base (hit f.connect on the base and then the controller), but ever since then it's automatically linked up. And if anyone happens to find a website for this company (or whatever company produces these things) please let me know, I'd like to find out if there's possibly an xp x64 driver out, I've gotten the 32-bit one to work for the moment, but I don't have a cp or anything, just the standard windows controller options
edit: found some more info (I <3 google) Game Elements is actually produced by Gemini, which is owned by Philips. Their webpage is here, but it provides absolutely nothing concerning our controller
