I have one and use it primarily for long solo rides. I took it with me to the area state parks to test it. For some reason the Spot gave incomplete data of my whereabouts in one of the parks. I don't know if it's because of the trees or what but I remembered that the instructions read to move to an open area or field if you are in a wooded area and I tried that and it still didn't send the info to hubby. Funny thing was I had cell coverage during that time and called hubby to check and see if he was able to track me.

The Spot is a good tool to have if you are offering sag support. I tracked hubby and friend's ride via computer and noticed that he had slowed considerably on his ride. I headed out to retrieve him and he was relieved to have the car available.

If you get one, before heading out on your ride, turn it on for about 10 minutes prior to the ride so that there's a good satellite signal. Then let your friends enjoy watching your journey.
