Thanks to the store. Quite fast delivery time. Everything was brand new and well-packed. Bought the M30 Bluetooth controller with clip for emulators on Android. Unfortunately the controller won't pair with my old devices (checked with 2 smartphones on Android 4.2.2 and Android 4.4.2). Anyway, it works well with Samsung Note 8 /S8 on Android 9. The downside of such setup - smartphone is too heavy in comparing to controller and it's inconvenient to hold it during long play session. Other inconvenient thing - it's not possible to charge the controller when the clip attached. Also, you can't see the red LED which indicates low battery. You have to detach the clip every time you need to charge the controller and it's not so easy to do as clip holds very well.
SN30 pro+ is the best controller you can get for your Nintendo Switch. You can trust me, I've beat Celeste. Nintendo's Pro Controller in comparison have a very poor d-pad and misdirect you so often, you want to smash it against a wall.
