I bought this for my seven year old grandson for his birthday and he just loves it. Jest to, 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. Muzyka. 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. O, 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. Jak ja, 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.
