Sorry tot the rick roll answered it.
With the gotcha, you can set it to spin stops OR catch pokemon OR both! You can also set it to auto catch pokemon, or set it to catch only if you click it (like how the go plus works).
DATEL is a good seller. I have gotten 5 gotchas from them over the last few years and they all still work.
We have ordered 5 go-tcha's from amazon with no issues at all. Made by Datel, the same ones you can get at gamestop. I have never heard of anyone getting banned for one. If you order on Amazon, just pay attention to the seller's name. Nintendo sells the go-plus, Datel sells the Go-tcha.
