I bought it last year for my boat and I love it. They only thing that you need to remember is to take it out of the boat or store it securely if you trailer. I got home from a trip and realized that it decided to part ways with me on the highway. I reluctantly followed my tracks and found it on the side of the highway with a few tire marks that (luckily) came off without any sign of damage.
Once you use it you will never want to ride without it. I sometimes will leave the launch and I can tell something is not right. Oh yeah, my Comfort Zone is still stored...
