The speed dial is absolutely awesome! My daughter struggled so much using the smart drive with the watch. She either had problems getting it connected, or figuring out speeding up and slowing down with the taps, which sometimes worked, and sometimes didn’t. The speed control dial makes it so easy for her to use!

Works nice very convenient. It’s out of the way so you don’t hit it by accident for the most part.— my only problem with this device is that when you mount it the wire should be on the other side but the design now must be careful of wire in front of disk whereas if u push the dial forward you will slowly rip the wire out

I found this controller is best fit for me so I can control low to high speed without tapping each time. I am so comfortable using this without wearing controlling watch.

This is an amazing addition onto the SmartDrive. Using the Speed Control Dial is how the SmartDrive should be used, and it’s wonderful.

My only gripe is that it was very difficult to install and there were no operations instructions outside of installation.

If you are considering getting the extra piece for $15, do it. I didn’t think I was going to need it but got it anyway, and ended up needing it.

Also, this may change, but as of when I purchased the product it took about 30 business days to get to me.

Worked great only thing is it eats up battery time. Otherwise it's great. Used at Universal Orlando helped out wife alot.

This is a game changer! It is so much better than the switches or watch. It is so nice to be able to slow down and speed up.

The dial is awesome, total control all the time. No more sporadic Bluetooth connections, no more banging your watch, just slow to fast and everything in between! I had the watch for years and the new one was too complicated. So glad I opted to go with the control dial. Makes the SmartDrive much more user friendly and easy to operate. Wish disconnecting the dial mount was easier when not using SD but otherwise the best investment I made.
