desertcart.com : SereneLife Thunder Wave Kneeboard, with Strap and Hook for Kids & Adults | Universal Water Sport Kneeboard for Boating, Waterboarding, Kneeling Boogie Boarding, Knee Surfing (Black/Blue) : Sports & Outdoors

Review: Easy for a first timer and super reasonably priced! - Our first boating season was 2024. We had a blast, and this knee board was the perfect addition to get us started before a tower is put on the boat. It floats, isn't heavy, and seems to do exactly what it is supposed to do. My sister had to try it, and she has never been on anything like this before. And after watching some of the kids, she was able to stay on and get up on the first try. She had an absolute blast! She said the board itself was comfortable and was easy to maneuver. Of course, her entire body hurt in the following days. Not from the board, but from the muscles activated that she had not used in a while. haha! She said it was totally worth it!
Review: Good Beginner Board - Worked really well for a beginner knee boarder.

Worked really well for a beginner knee boarder.

### ⭐⭐⭐⭐⭐ Kids had so much fun.
*by L***N on July 26, 2025*

I figured I'd order a knee board for my grandkids, because they're into a lot of sports and there's 7 on up. The first time trying and they went around the lake once and they're standing up on it like a surf board.They love it. For them they can't yet grasp the knee strap, which is extremely long. so they go without. 7 yr old standing after 1st try
