Controlador de anillo de dedo de doble motor subnado

Works as it should, so far so good.I like it

This is a must have if you plan to use 2 on a paddle board. I mean you could use 2 individual controllers, but then you have to make sure they are both in the same mode for speed. Just make your life easier and get a 2 to 1 controller if you're using 2 on a board or kayak.

Used it two times and both time have problems. It works every other time, but most time I have to press it 3-4 times. very disappointed. How to return ore exchange it?
