Strap needs to be adjustable.  I have an 8 year old and a 12 year old and their hands are totally different sizes.

i use this kickboard mostly for side kicking.  you really need a snorkel with it for freestyle swimming,but i"m getting adjusted to raising my head above water for air.  It is light weight and can be used under water during flip turns.  If you have a bad back it keeps your spine aligned straight.

The worst kickboard I ever had--no instructions of substance. Go with the good old-fashioned kickboard. Save your hard earned $$.

great with a snorkle, but hard to use without one.  for extgended face down kicking laps, this is good, easy on the shoulders, reduces the strain of larger kickboards that force your shoulders up at an uncomforbable angle.  But, you will want to use a snorkle, it's hard to breath otherwise, as this allows your head to be lower in the water than the larger boards, and you will have to keep changing your position to raise up for a breath.

I swim with it almost everyday. It does exactly what the manufacturer claims. It glides very easly through the water and it helps keep proper position and alignment in the water. I would recomend using it with their snorkle since it floats a few inches under the surface you can't keep your head out of the water as with other kickboards.

This is a really helpful tool.  My shoulders are stiff as boards, and I have trouble feeling a streamlined position. I used this kickboard with snorkel and facemask, and was able to focus 100% on strectching out my arms with good hand position.  What a dramatic difference!  Thank you Finis and thank you Swimoutlet.com.
