  • Great product! It has me back surfing regularly.
Color: Boost Fin
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. ... show more

  • Legit!
Color: Boost Fin
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. ... show more

  • Company Customer Service not good.
Color: Boost Fin
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 ... show more

  • Paddle boarding for pleasure and ease. Get a Boost!!
Color: Boost Fin
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. ... show more

  • Boost fin looks good and is well built, but doesn't provide much power or usage time.
Color: Boost Fin
The best aspect of this product is it's design and packaging (not the box it came in, but the product itself). It's a slick, well thought out design. The build quality seems good and it feels solid. Everything is sealed and integrated. No wire connecting it to a separate battery pack. There's also an app for your phone that will tell you the battery level. Don't know if the provided screw driver needed to turn on or off the unit is a good or bad feature. It's cool and keeps openings to the water to a minimum, but what happens if you lose the screw driver? I had to spend another $40 for an adaptor for my SUP. I've used the fin on my SUP in water that was flat and with 4" waves and a current. In flat water it's ok. I can definitely paddle faster, but it's good for a leisurely ride. When I ran it in 4" waves with a current, it barely was able to keep me moving forward. The battery life is not good. Makes sense considering the limited space in the fin. It only ran for ~30 mins at 100%, again at a leisurely pace. Running the fin and paddling together makes for a good pace. In burst mode, it's good to get you going from a stop and this might be the best use for this and if you are on the water for a long time (>1 hr). You could also use it only for the return trip when you are tired or going against the current. Would I spend the ~$500 (+ $40 for the adaptor) for this power fin again? Probably not, but I'm not so unhappy with it enough to return it. Similar products are either much more expensive, or you have to buy a separate batty pack, or don't look as well built (without actually trying them out myself). This might be the Dyson of power fins. Looks good, kinda expensive, does its job ok. ... show more

  • It's GREAT!
Color: Boost Fin
I just received my boost fin, and it looks great. Took a minute to figure out how to lock the fin to my new iRocker board, but once I figured it out, the app set up and everything was super easy. It was a perfect day with a nice breeze and I was able to get 2, 20 min sessions before it got dark. My arms weren’t even tired yet! The boost offered great support and I might actually keep my new year’s resolution to get out on the water more, knowing that boost is there to help. For those interested, works well with a 10.6’ Blackfin board...once I figured out how to lock it on. ... show more

  • Fun addition to a paddleboard
Color: Boost Fin
This has been a lot of fun. I had to file down the piece that fits into the board but once I got that in the rest works great. It took a minute to figure out the speeds. It is basically full throttle or it does a pulse thing then stops. Hard to turn the paddleboard at full throttle so I turn it off to shift direction then start again. ... show more

  • Kool toy

Works pretty good. Not a power outboard, of course. Maybe two hours of function, or less. Not for a performance surfer, it will have some drag. A hot shot surfer shouldn't be using this anyway. I am figuring out how to carry a magnet with me, because the fin shut off while out in the water and I couldn't use it for that session ... show more
