Great boats. My husband and I have had ours 7 years. Indestructible! A very stable boat yet tracks well. The only reason I don't give it a 10 is because it is a little heavy. That might be my problem and not the boat's!
We used the mule twice and it developed a leak at the seam. We called the company and they sent out a new one immediately. Nice service! The new one does not leak!
This is a great idea...and when it works it is very convenient but a number of times my Gription leaked. Sometimes in my car or backpack. I finally threw it away when it leaked in the tent!
