My twin boys had an upcoming birthday, and I thought they might enjoy kneeboarding behind the waverunner. I was right! After opening their present, we watched some online beginner kneeboarding videos and hit the lake to try the new board out.This board is constructed, and more importantly, designed well. The knee pad is just the right depth and placement on the board to keep the nose at the right angle, the adjustable strap is heavy-duty and easy to grip and adjust in motion, and the tow rope holder at the front of the board allows the rider to get into position and strapped in using both hands before grabbing the handle from the holder to begin your ride. The board's length and width provide plenty of onboard stability.Everyone was able to get up and ride on their first attempt and by the end of the day were surfing over the wake and slicing through the water. Fun!

This is a great kneeboard! The square front helps a lot with balancing on the water. Very easy for my 9 and 11 year old to use, and they have minimal experience with water sports. The price is great, the quality is great, and I would recommend this product!

We’re happy with this for the price. It could use a little more padding for the knees but it’s a fun kneeboard.

Great quality knee board…it is easy and super fun. I’m 6 ft 200 pounds and can do it with no problem. Even had my black lab and Australian Shephard on there with me. They loved it. I’ve taught several people on it so it’s good for beginners and the average person.

Attempted to get a replacement for a defective board- the covering on where you put your knees peeled up -= purchased this product 3 months ago - contacted the company and supplied all documents that they requested and then they would not respond to my emails - never got any replacement board or any further correspondence - very poor customer service

I recently purchased this kneeboard because I thought, "How hard can it be? It's like wakeboarding, but sitting down, right?" Wrong. It's more like "wakeboarding's awkward cousin who shows up to the family reunion and immediately trips over the punch bowl."First off, let’s talk about the board itself. It’s sleek, colorful, and looks like it belongs in an X-Games commercial. Unfortunately, it came with no warning labels about the likelihood of accidentally inventing new ways to wipe out. You’d think the flashy design would intimidate the water into submission, but no, it just makes my inevitable tumbles look even more spectacular.Mounting this thing was a comedy routine in itself. After flopping around on the dock like a seal trying to put on a wetsuit, I finally managed to strap myself in. You know those instructional videos where people gracefully glide across the water with the confidence of a swan? Yeah, that wasn’t me. I looked more like a panicked cat trying to avoid a bath.But once I got the hang of it (and by that, I mean after a dozen or so failed attempts and a few gallons of lake water ingested), I must admit, it’s a blast! The kneeboard is sturdy and responsive—perfect for those brief moments when I’m not flailing wildly or yelling "Why did I think this was a good idea?" to the open air.And let’s not forget the workout. My core, arms, and pride have never been more engaged. By the end of the day, I was more exhausted than a toddler after a sugar crash. But, I have to say, there’s something exhilarating about crashing into the water at high speeds. I’ve become quite the connoisseur of belly flops.Overall, this kneeboard has been a humbling experience. I’ve learned that water sports aren’t just about looking cool—they’re about surviving long enough to try again. If you’re looking for a way to test your endurance, sense of humor, and ability to get back on the horse (or board, in this case), then this is the product for you. Just be prepared for a lot of laughing—mostly from your friends on the boat.
