Review on 🧜 Mermaid Monofin - Fin Fun Swim Fin for Kids and Adults: Boost Your Aquatic Adventure! by Douglas Holla

Excellent product! Only rated 4 stars because it was too small for my foot (size 44) but my kids (size 10) could put it on with no problem. They can move throughout the pool, only limited by their ability to hold their breath. The first few moves were a problem and resulted in a lot of "whale failures," but they managed. This can hit her very deep and very fast, and we had one instance where she grazed her chin when she unexpectedly got too close to the ground. Bring good goggles or they will leak when you change speed and depth.
