This thing works. Paddling out used to drain me big time, with boost it's way easier - now I have enough energy left to actually catch a wave afterwards LOL. I tried to get to the lineup on boost alone, without paddling myself: it works, but takes a while - so I usually use the fin and paddle simultaneously. It also helps to catch the wave, but you have to use the higher speed setting (there are two buttons, regular and high) and learn to time it correctly. It's obviously not magic - you still have to paddle hard. But the difference is significant and for me it’s a game-changer. Gotta mention that I'm new to this and use a 8ft board, not sure how this would feel on a shorty. I would certainly recommend it for anyone that's at my level.

Received quickly from Amazon, works better than you would expect. Getting mores waves, less paddling required. Easy to install, app is user friendly. The app has a setting that can be adjusted for power and time needed, Example I set mine at 110% for 11 seconds that helps get me in the wave quickly. For paddling out , there are several settings I set mine at trolling. At this speed I personally get a solid hour and 15 minutes with a minimum 8 waves. I’m not an experienced surfer and I’m sure the results are different depending on your surfing level. Great customer service, been seeing them everywhere lately even saw one in Hawaii. John c,

Company Customer Service not good. The actual fin is fun. The fact you have to purchase adapters for paddle boards is disappointing. Major issues are the wrist control doesn’t fit adult wrists and there is not any flotation device on it. We ordered a floating wrist separate and put them on that strap. The company knows of this flaw and doesn’t care. Also the controller to turn the fin on and off is a magnet inside of the screwdriver, for an additional purchase you can have one that floats. Since we are traveling with this fin and our paddle boards we found an alternative way to turn them on. Again the companies response was don’t take it in the water. Sure however that is not practical for our use. Overall it’s a water based product that they didn’t seem to consider it would be on water. I also suggest buying the $30 leash for the fin if you are using it on a paddle board. It’s definitely disappointing for this price… great idea hopefully someone builds it better

Great. Did the job I bought it to do. I enjoy water sports. As the years keep ticking away I still want to be in or on the water. The paddle board is a great place to spend a couple hrs The Boost really helps Paddling into the wind or current. One can take a breather for a few minutes too. The Boost power you around. It’s really easy with the remote control on the wrist. You take a spin on it you will want it. Easy to install on the board. First take long. It does energy for 2 hs depending on current and usage.

I wasn’t sure if this product would deliver on its promises, but it has far surpassed my expectations! I suffered several shoulder injuries, two requiring surgery. My paddling strength after the operation was very low. Surfing was just frustrating. After installing the Boost fin I was able to catch waves again and regain my Stoke for surfing! It works quite well on my 7’ Aipa. I’ve also used it on longboards and SUP’s. It’s worked great on all. This fin helps with paddling to the line up and catching waves. Also cruising on a SUP. It does create a little drag while surfing, but it’s worth it considering how many more waves I’m catching. The best part is that using the Boost fin during my shoulder recovery allowed me to develop and recondition those muscles and now I’m back to surfing on my own power, but I still enjoying using the Boost fin on about half of my sessions.

First class packaging, nice looking product and looks well made. My issue was battery life. Took it out for a hour or so paddle, maybe hit the boost button 20-30 times for short, less than a minute boosts and ran out of power. At most used it for 30 non continuous short bursts boost and that was it. No where near the “up to 2 hours” the website said. Don’t know how long running it continuously would’ve got me.

The Boost Fin is a game-changer, especially for older folks like me who want to enjoy surfing without overexerting themselves. It has made surfing so much easier and more enjoyable—just like it used to be! The app is a fantastic addition—I was able to pair my motor, adjust the mode to my liking, and monitor the battery life. Setup took just a couple of minutes. Highly recommend this to anyone looking to enhance their surfing experience!

These work great. A few wish items- they need better waterproof plug system and more board adapters. App and wrist buttons could be a little more intuitive. They are slightly loud on the water. 3d print profiles for adapters would also be nice.
