Love the board! I've been kayaking for the past 4 or 5 years and standing up is awesome! It feels very stable on small inland lakes, even during windy conditions. I have yet to try river boarding, but I feel confident this board will work well.
It's light, easy to carry, and moves well in the water. The foam padding on the top is gentle on your feet and knees.
As I've said, I love the board. This comment is in general. I didn't realize when I made the purchase it should be stored in a relatively cool area. Michigan summers can really heat up a garage. So, identifying a decent storage place is my only complaint.
The board was purchased for recreation and exercise.
