We absolutely love these electric fins! I purchased 2 of them in August 2024. We have used them on fresh and salt water. The batteries last as advertised. We recently used them on the ocean in lots of floating seaweed and shallow areas of the Florida Keys. No problems. Used reverse to clear seaweed when needed but never got clogged. Traveled 8 miles on a paddleboard in breezy, choppy conditions, against tide. Battery lasted 4.5 hours! During storage over the winter I charged the batteries a few times. When we went to use them last week the remote batteries were dead. I was able to pry it open and replace the batteries but it didn’t look like they were made to be opened and wouldn’t snap closed again so I used electrical tape to seal them closed again. Worked fine. I don’t see a way to order extra remotes but would like to buy some extras. It looks like this product is unavailable at this time. I hope they restock. Great product.

The media could not be loaded. Got it for my spouse so she doesn't feel like she has to exhaust herself just to keep up with me and I don't have to remind myself to slow down. I was a bit sceptical of the device and did not have high expectations at first. I was pleased to learn that it works as advertised. Environment: we use our SUPs on a local river with very slow flow of water during summer months. There are weeds and occasionally they will get stuck in the propeller housing. If that happens stop the engine, pull out fail-safe so it doesn't accidentally starts and have your partner reach under and clear weeds out. You can do it by yourself but with the battery pack obstructing you might have difficulty doing it yourself. Set up: putting everything together is easy, but it helps if you have a partner to help carry the device, battery, attachments, as well as the board and the paddle. The remote and the device sync immediately and work very well to control the motor. Tips: get yourself one of those soft African weaved baskets so that you can carry all of the stuff and then keep the basket on your SUP, attached. Speed and battery: we were able to get almost 2 hours going 5mph or 7.5kmh on high setting. This is definitely fast enough for my spouse to keep up with me and even wear me out, going at full speed without the motor for this long. We did not run out of battery during the two hour sprint. According to the instructions we could do 5 hours on low speed, but we haven't try that yet. Battery charge time is as advertised, under 4 hours. Experience: my spouse really enjoyed it and felt like she could focus on the nature, sky, birds and enjoy the SUP ride instead of catching up with me. She went with me several times much further than we would typically go together. As for me, well, I just enjoyed watching her effortlessly go right next to me with a smile while I am "working out" on my SUP without the motor. A few times during our rides the high speed mode changed to low speed automatically, but every time this was due to a leaf or a weed getting stuck inside the motor. I hope it keeps working as it goes. One thing that I think they could improve is to add some kind of battery gauge to know how much juice is left.

The fin itself is nice but the adapter is made of poor quality and shattered when first used.

Great long lasting battery and sufficient thrust on the electric fin motor of around 18 lb-ft. The product definitely makes the paddling easier, especially if you have to balance a pup on the board. Don't forget to charge the battery to full every few months to ensure long term stability of the product. The water proof battery box is also great and comes with a good harness system.

Working good. Wish the battery had a charge indicator. Will update. Update after one year. Remote is no longer working. No way to check the battery in sealt remote. Canary to order new remote for $40. No confidence in product. No customer support. Just got the new remote. Works great. Change rating back to 4 stars.

I must rewrite my review for the product and their costumer service. After two months of using it,I love the product, it truly made my paddling, enjoyable and efficient as well as effortless! Their customer service was very good in reaching out and helping me to replace my remote control. I would definitely buy again from them. Highly recommended.!

This LEDONNE SUP Electric Fin Underwater Thruster is a game-changer for paddleboarding enthusiasts! I was amazed by how easy it is to install and use - it fits perfectly on my paddleboard and gives me that extra boost when I need it most. The battery life exceeds expectations, lasting through my entire day on the water. The underwater thruster provides consistent power without being too noisy or disruptive to the natural paddleboarding experience. I especially love how it helps when paddling against currents or when my arms get tired during longer journeys. The design is sleek and doesn't add much weight or drag to my board. The waterproof construction feels very durable and well-made. Overall, this is a must-have accessory that has completely transformed my SUP adventures and opened up new possibilities for exploration!

This powered SUP fun is nice but not as advertised. The battery life is as advertised. It will last for five hours on normal drive mode. That means you can spend a good amount of time paddling around and having a good time so long as you only use the drive mode. The advertised speeds for the drive and sport mode settings are nowhere near the advertised speeds. I could barely achieve 3 mph on sport mode with a tailwind. Overall, it is a fun addition to a SUP, but in my evaluation not worth paying the normal pricing for it. Wait for it to go on sale if you’re looking to purchase one. I would give this product a five star rating if one of following scenarios existed. 1. The product actually produced the thrust necessary to achieve the advertised speeds. OR 2. The price point were around $300 for the current product. Again, not worth the $400+ price.
