Remote recommendations for VESC6.4

I got this VESC 6 (

and this remote control, the maytech one with the thumb push button:

I am disappointed by how flimsy the remote feels and I can not get a good connection between the remote receiver and the VESC. Sometimes it works, sometimes not.

It is so frustrating.

What sort of remote + receivers are people using with a vesc 6 that they are happy with.

Thank you
