Picked up the Otter at Costco two years ago. The paddle board is stable for beginners yet narrow enough to get some good speed. I use it mostly on a large lake when wind and boat traffic can be challenging. Only once have I taken an unexpected swim due to losing my balance. Overall it is well-built and easy to maintain. I added a bungee cord deck rigging to keep beverages, sunblock, etc. in place. Love it!
Stable yet reasonably fast. Well built.
The included paddle is fair. Upgrade to a carbon fiber paddle and you'll have no regrets. I wish the deck rigging was included but it was easy to add with a kit that includes all necessary parts and adhesive.
I use it primarily for exercise and recreation on Colorado lakes.
