I do not ride without FlightFins! They are the best OneWheel accessory on the market. If I didn't have the FlightFins on my XR and GT I probably wouldn't OneWheel as often as I do. They make it more fun, safer and give me options when approaching different terrains. Are they worth it? What do you think. I'd skip a few meals to get these things if I didn't have the money. They're that good. I ride my boards with fangs and flight fins with extenders. The company is rad and the customer service is great. Don't sleep on these FlightFins. You can teach your kids to ride just by having them stand on the fins. By the time they try it on their own, they already will understand the balance of the OneWheel and learn it instantly.
