The vx2 is a pretty crappy remote.
I would suggest you not buy this and get a vx4 instead which is much better.
That said it works OK once you do this tweak to your vesc settings:
So if you don’t have much money you can buy this for $50 Canadian which is about one third of what a new one would cost shipped to Canada with tax. I’ll pay the shipping.
If you are in the US it’s $60 US since the shipping will cost more.
