I purchased this as a gift for my nephew because his XBOX One Controllers were never charged up. I was very happy that this included the Dual Charging Station and Two 1200MAH Rechargeable Batteries, which means he has a battery for each of his two XBOX One Controllers and can charge them on the Dual Charging Dock at night so they are charged up and ready to go the next day. Even if I had paid full price for this product, it would be well worth it. We have already saved over $300.00 in batteries by purchasing this. I am looking to purchase a second one of these so he has extra Rechargeable Battery Packs and an extra Dual Charging Dock because he now has four XBOX One Controllers. I would also love to see this Seller release this same thing for PS4 Controllers and I would purchase it for sure. I will be looking for more products and coupons on Viralix.com from this Seller. Highly satisfied with my purchase!
