    I bought 4 fins for my granddaughters.  They LOVE, LOVE, LOVE them!!  But...two of them have cracked from the center curve.

    This product is so much fun! I bought two of them and should have bought more as other kids want to try them too! The kids are having so much fun pretending they are mermaids in the pool! Awesome invention!

    Granddaughter age 11 has these comments. She loves it and has made a mermaid fin to cover her legs with mono fin inside. She wears it when she goes swimming and is an excellent swimmer. These are her suggestions. Make fin wider where feet fit~Make buckle flatter and out of firmer material~Make barrier between feet a little taller and extend a little further back~Plastic is brittle breaks easily~ Make back strap a little longer so older kids can wear it~Make fin a little larger such as 1" wider and 1" longer.  Make same style in an X-Large.

    Really doesn't stay on our little dolphin girl's feet very well.

    I have made her a mermaid tail bottom to wear with it and she looks just like a real mermaid in the pool,  just has to learn how to swim better with it on.

    My 9yr old daughter loves this fin. Her friends love borrowing it at the pool. We have even given it as a gift. The only thing is their feet can slip out of it..while swimming even with the adjustment but once they are in and not slipping out.. it gives lots of enjoyment. Great swim toy! So fun for a girl to feel like a mermaid for a little bit!

    My daughter is 10 and obsessed with mermaids.  I got the Finis Mermaid monofin for her birthday.  While its been unseasonably cold, so she hasn't been in the pool yet, she is soooo excited!  She will wear it in the car, with her fin on the dashboard... Or lay in the floor with her "tail" behind her up in the air.  I haven't seen her get that excited in a long time.  It's a starter fin, but seems to be made very well.  We wish the box it was delivered in had been smaller since they used a gigantic shipping box... But it arrived when promised and its wonderful.

    My daughter has been wanting a monofin so she can swim like a mermaid for months on end.....too bad this didn't help!  She can get (mabey) three strokes out before the fin slips off.

    I have small feet and thought I would give it a try.  I wanted to see if it was the product or my daudghter needing to learn to use the flipper.

    I couldn't keep it on either.

    The single strap across the back would be better if it were two straps, holding each foot in place.

    I ordered this fin for my little cousin's tail who immediately fell in love with mermaids the moment I showed her my tail. While she has not gotten the chance to swim in this fin quite yet, she tried it on and it fit great! Not only was the strap soft to the touch, the foot pockets are made of nice and flexible rubber. The fin has an adorable little shape that really makes you feel like a cute little mermaid! The only donwside is the strap os a tab hard to adjust and has a tendancy to fall off if splashed to abruptly. Overall, my little cousin and I are very pleased with this monofin! 3

    This is a really cute design and very affordable as compared to other mermaid fins. I bought it for her birthday and imagine our disappointment when her feet were too wide to fit it. She wears a size 3 so there was plenty of room in the length but her feet were 3 inches away from going in the whole way because of width restrictions. She tried to use it this way but it didn't work. kindly sent us a replacement in case ours was defective but it was the same. I titled this "narrow feet required" because my daughter does not have wide feet. I would say they are wider than some but we do not have to buy her wide width shoes.

FINIS is Latin for "The End" or "Finale", and it signifies in the name of this company both the developmental goals that swimmers have and the end that they strive to reach—the finish line. Founded in 1993, FINIS provides highly technical competition suits, training equipment, child water-safety products and high end goggles. Their very popular SwiMP3 water-proof digital media player is revolutionary in its streamlined design, enabling a swimmer to listen to music while practicing laps and other exercises in the pool.
