I purchased these for my 3 and 5 year old after a friend of mine recommended them. Apparently a lot of swimming instructors use them. My kids love them! They teach kids how to be in the water on their bellies vs arm floaties where they just stand in the water with their arms above the water. My oldest has already removed one of the blocks and is swimming really well. Highly recommended! 5 stars

my son is now 2 yrs old have been using this float system for 6 mo now and I have removed 2 floats already!! Great support and great teaching aide for swimming. My son has confidence now and is no longer scared to swim with float to deep end of pool. Highly recommended. 5 stars

This is an excellent teaching device. It provides great support for a young child learning to swim. It is very easy to remove one of the floating devices as the child excells. It is also very easy for the child to put on and take off. I would highly recommend this device. 5 stars

i bought this for my 4 and 5 year olds after i saw my friends daughter swimming with one. they put them on and right in the pool, they use them all day everyday with no problem. they used to use life jackets but were unable to really swim, they could float but not swim. now the have full range of motion in there arms and can swim for real. great product!!!!!! 5 stars
