Bought a Go Cruise from Amazon, it was delivered on Tuesday. I had a couple of out of town jobs so I got to try ou the device. What a remarkably simple, yet effective device. My first trip was 120 miles round trip riding CA99 both ways. Speed limit is mostly 70 and the Go Cruise was flawless. Just a few minor speed corrections but it really worked well. My next trip today was shorter and mainly back roads, 85 miles round trip, 55 - 65 mph limit most of the way. Again it worked just great. Tomorrow Im heading back to the Coast about a 400 mile round trip, and it should really alleviate the fatigue I had on the last trip.
For $20 bucks it is really a fantastic device so far. Id recommend it to anyone looking for some sort of throttle lock/cruise control device. Not sure about how long it will last, but for $20 if it lasts at least a year Ill be happy.
