Instructions on how to inflate are misleading, it suggests a bicycle pump, and this doesn't work.  The valve stem is not threaded.  What does work well is a portable electronic pump for a car.  This did the trick right away.  Because of this difficulty, the manufacturer's suggestion of inflating and deflating as needed isn't convenient.

The product itself is made very well.  There is an adjustable bottom part that velcroes.  It was difficult to get it over my toddler's head, but just needed some finesse.  Still completely worth it.

My son (18 months) is not used to being in the pool, so he tended to lean forward on the tube which made it tilt to a vertical position.  This left the potential of holding his face in the water if you didn't hold the tube.  This was easily overcome by holding the back of the tube the whole time.  I think once he is used to the water and "feels" how to hold himself up with the tube, it will be much better.

Overall, I am pleased with this product.

My two children are grown. We had these swim tube trainers that not only gave the children confidence it made us feel better that they were safer while in or around the water so we bought one for our grandson. It is easy to put on and easy to remove! I highly recommend it.

I bought this for my 2 year old grandson. He's able to kick with his legs and use his arms to move all over the pool.  He has great fun.
