Not much flotation from this.  need to be able to move at a really good clip, or keep your head in the water.  not for folks out for sunday stroll in the pool.  this is for people who are working in the water.

This board is really cool.

like that it is light weight and easier to carry from pool to pool

Supports enough when kicking without having to 'fight it' and fits well in the swim bag.  Substitutes well as a pull buoy by slipping between the legs when I pull on the training gloves for an upper-body workout.  Good design and size...Bravo !

This kickboard is lightweight and it moves through the water very smoothly. I like the surface texture, it is easy to hold onto.

Other boards would cause my shoulder and lower neck muscles to ache.  This board has awesome grooves for your arms that are very comfortable and prevent the muscle aches.

The board is also very hydrodynamic .

I've been swimming for a while and this is my favorite board so far.
