Universal cruise control

Anyone have any experience with universal cruise controllers (similar to below).


Have the iron butt this weekend, and thinking about getting one but all views welcome.

I’ll bring a cramp buster for you to try, I love mine, takes a bit of getting used to as the throttle action can become snatchy. I also have the £40 universal thumb lever type, I couldn’t get it to work properly, I’ll show you that too. I saw a lad at Walkers last summer with the £20 lever that latches on to the brake lever, he said it didn’t work as you’d expect, too much of a fiddle to set and lock.

Cheers @National_Treasure very much appreciated.
