I purchased the Xerc 2 for my xbox. There was a shipping error that was my fault but they quickly, and I do mean quickly return shipped to me!
After reviewing the installation instructions from their website, I mounted and soldered my Xerc 2 and it is freaking awesome! As the xbox sits powered off, my power light slowly fades on then off! And I can turn the xbox on with my home remote!
For anyone out there considering a IR upgrade for their xbox with bonus features at a terrific price with fast shipping, I HIGHLY recommend the Xerc 2!
