This is definitely one of the best investments i have made. I even stood on the bag while inflated and it did not pop (i am 190 pounds). This is essential for every swimmer because you really don't know what can happen in any given circumstance. Sometimes even pro swimmers struggle to stay up which is why i think refloats is a need!
Refloats are very comfortable on the wrist and make you feel secure when swimming. I'm not afraid to go into deeper water when i have on the refloats because it really does work. It's also awesome for beginners who are trying to learn swimming.
After you use refloats, it is easy to fold and put back for later use. I tried the whistle which was super loud and the balloon was able to carry me up to the top when i swam very deep.
The packaging is really good and the floatation balloon inside feels very strong. It feels rip-able and inflates very fast.
Material is extremely durable and feels unbreakable, they also had fast shipping and excellent customer service.
