Wii U Nyko Charge Dock Mini is a good charger for your Wii/Wii U remotes. The battery slots into your remotes quite well and they are secure. The batteries aren't heavy and don't weight down the remote. The life of the batteries is this products down fall however, the two batteries are only good for one remote, due to the fact you will need to swap them out during extended play, with that in mind buying a Nyko dock for each remote isn't practical considering the price tag, hopefully Nyko will release battery packs for sale, as that would solve the problem.
