it really works fine and is great, maybe it feels cheap but it does the job just fine and battery lasts as long as normal batteries. But the issue is that they are hard to remove or put back in, which worries me into damaging the controllers. Other wise the design wasn't the best of having a 2nd usb-c entry on the battery which is totally useless since the controller already has its own entry, In my opinion is that in the end, it's best to stick with products that are licensed with xbox if you're looking into accessories for your gaming console. In my case, i just took it because i had no choice since i couldn't find any at all everywhere which i now a little bit regret since it just restocks for better ones for cheaper and better price I hope this helps !
Everything is great and works fine
The batteries are hard to put and out, worried about damaging my controllers if i do it often
