The product has just arrived; it hasn't been used but i have inflated it. It is much smaller than I imagined. Although it is roughly the diameter advertised it is definitely not the same as the ones in the images. Aside from the fact it says "My Baby Ring" not "My Baby Float" on it and there is no writing on the inner ring (completely insignificant but indicative of the fact it is not as advertised) the outer ring is far narrower with only one tube rather than the double width tube shown in the pictures. The headrest is also much less substantial. I am therefore concerned my son won't be as secure as I had hoped and imagined. I guess you get what you pay for and I have bought this for a holiday, hopefully it will do the job and I will probably leave it there.
