EDIT: I added the decompiled source to the file, it was made in .NET.
This also has a serial checker included in it.
When you get the serial of the product you want go to Logitech's website or Ultimate Ears website and register the products serial. Then contact support and make up an excuse on why your product isn't working.
If they say sent it back or sent a picture of it broken (as which Logitech does sometimes so they will send it back as they see it broke) just say you got blood on the device as you were packing it up. Don't use this method to the same address.
