So I found this today and am very confused. I thought all prototype XBOX 360 controllers have a white jewel on the front. When I opened the battery pack I noticed it is a Radon DV1 because of the sticker. It is also missing the manufacturer sticker in the inside and on the outside top it is missing the Microsoft hologram sticker.
Drachir got what he has from me. No, not all prototype radon or krypton have the white jewel. Some early models are missing a jewel completely while late models of both have the final jewel. Think of it like the alamo, then Dakota and then the B2 controllers. You have just found a very late model radon which is the same as a krypton, only wireless.
