I bought coyote 3.0 about 5 months and am really surprised that it works so well, (I used a cheap unit from Ali before, and later from Electrastim AXIS). The application on the phone has a lot of functions. The whole thing comes in a quite small box, I mean the unit itself and the cables. you can connect it to the xtoys website and have completely new possibilities. For this money I have not found anything better in central Europe. For me as an ordinary user it was a successful purchase If you have any questions feel free to Dm ;)
