This seem legit to you guys? Looking to get one of those adapters, and for that price...
(I never shop on eBay, that's why I'm asking.)
You can't buy Official loose 360 Wireless Receivers for PC anymore. The only way you can find one is by either buying a used one or buying a 360+Adaptor kit - They're sold as Wireless PC Controllers.
HOWEVER, every single official 360 wireless adapter for PC has a problem with a fuse that, eventually, blows up, rendering them useless (until you either replace that fuse or bypass it entirely). On the other hand, all the fake ones work. I've been using one for YEARS without a single issue. Some of them are instantly recognized by Windows, others require you to manually install the drive for them. It's easy and quick to do it, and the computer will recognize them forever after you manually install the drive at first.
On the plus side, they're also available in a myriad of colors, are cheaper and usually have free shipping. I would just buy the cheapest one. I wouldn't even care about the blister box, to be honest.
