I bought this for my seven year old grandson for his birthday and he just loves it. It’S, not heavy it’s, perfect size, even my two year old grandson uses it. I only wish it had a longer battery life before having to charge again. I have since ordered two more. We all can use it. Adults and children well worth the price. The package was delivered on time and everything was in excellent condition. Music. I also like the storage case to store it for the winter very nicely packed. I did take, buy the extended warranty package for all of them: the perfect gift Music. Oh, my goodness, what a perfect device for my family we’ve only used it in our pool so far, can’t wait to go out to a covet. Like me, my seven year old grandson thinks it’s amazing, great bonding tool and i’ve seen his breath. Control improve greatly he’s a new swimmer this summer.
