I use this pump to partially inflate the pontoons on my inflatable boat. This pump is very fast and brings the pontoons up to about 1 psi very quickly. I then switch to a true high pressure pump to finish off the chambers with 3 psi. This pump has enabled me to cut my inflation time in half. Great for float tubes also.
Assembly was more difficult than expected. The filling is shredded foam and filling that really needs to be broken up a bit, as it is very "solid" even after letting it "breathe" as directed. Orienting it into the colored bag is awkward, and we got it wrong the first time. Also tough to know how much air to inflate. Part of this is inflated, and part is just the foam, and it poofs around your head if there is too much air in it. Your whole body is pretty much out of the water on this, as shown in the pictures. All said, my daughter loved it, and there is room and float-ability for an adult and a child together.
As other have said, it is a good sturdy float and lives up to most of the qualities it advertises. The only problem is it really does not hold up a normal size person from being at least, a bit in the water. I would say, if you don't mind being in 1 inch or more, it is great. If not, just buy the cheap inflatable ones that you get each year for $$ and that way you stay out of the water. I bought 2 of these quality ones and need to stack them to stay out of the water on cool water days.
