I have not heard of this one but there are others out there, like the ThrottleMeister, that use this same approach of a locking/friction mechanism on the end of the grip.
Others, like the Vista Cruise & Breakaway, use a mechanism on the inner portion of the throttle grip.
I guess what gripes me is companies representing this product as a "Cruise Control", which it is not. It is a Throttle Lock, a very different thing.
A throttle lock does exactly what it states. It sets the throttle at a certain point and that's it. It does not maintain speed, only throttle position.
As long as nothing changes, wind, slope (up or down), even seating position/wind resistance, then you will maintain the same speed.
But if any of these variables change, so will your speed, sometimes quite a bit.
A Cruise Control automatically maintains a constant speed regardless of any changes in the variables listed above (usually within +/- 1 mph). Typically this is done by a vacuum or electic motor connected to the throttle linkage. This is what you have in your car.
Calling a throttle lock a cruise control is (to me) very misleading. I have nothing against a throttle lock. Some are designed very well and do a great job of locking the throttle. But they are not a cruise control.
