Review on Fosmon Controller Compatible Controllers Rechargeable Xbox One for Accessories by Chris Benton

I bought this because I have a lot of old Xbox One controllers and got tired of changing the battery every few days. The controllers easily snap back on for charging and stay in place unless something hits the table really hard. I'm tempted to get a second one as I have about 8 controllers at home for my 3 different Xboxes for my kids. The only downsides are that they are white only, the batteries themselves are not replaceable. Once the battery dies I guess I'll have to throw it away and these packs only fit Xbox One controllers and not the newer Series X controllers.
