The official Pokemon GO Plus for Pokemon GO has been a solid product, but the company Datel, creators of the Action Replay, decided that they could do better. Datel released a Pokemon GO Plus competitor called "Go-tcha" that I review in this video.
For the most part it functions the same as the Pokemon GO Plus, except for a couple of additional features as well as a rechargeable battery. With minimal configuration, the Go-tcha can spin Pokestops and attempt to catch Pokemon without the need to press a button on the device
