When I first tried H20, I was skeptical of its claim of silicone quality lubrication without silicone. However, I am glad to say that from my experience it has met those claims. My partner and I use H20 as our main lube and it works well as a mainstay. We have never experienced staining with it. H20 feels wonderful in penetrative play and we have never needed to stop to reapply. It is almost perfect.
It does, however, get sticky when used for male masturbation. So if you are a guy looking for a solo lube, H20 probably is not the best pick. It also tastes fairly bad. I recommend washing up after using H20 as it does get sticky after awhile and is not pleasant to wake up with on your parts. I have found that it cleans up easily with warm water. We have used it with all sorts of toys and it did its job well. One bottle will last you for a long time so it is a good buy.

H20 does contain parabens as well as the dreaded ingredient glycerin so, those with sensitivities to those should stay away or use with caution. However we have never had a problem with it, for what it is worth.

The ingredients in H20 are:
Propyl Paraben, Methyl Paraben, Sodium Carboxymethyl Cellulose, Glycerin, Purified Water.

-Sodium Carboxymethyl Cellulose is used mainly because it has high viscosity, is non-toxic, and is hypoallergenic. It is used in all sorts of things such as K-Y Jelly, toothpaste, laxatives, diet pills, water-based paints, and even ice cream.

The flip lids will leak if the bottle is left on its side, and it will get a bit harder to clean if left to dry on the table because you didn't know it had leaked.

I still like this lube, however my hubby and I are branching out and trying different lubes. Part of this is to find a lube that is good for the things this is not. Part of it is that being on Eden has made me want to me more adventurous. So far nothing has ousted Jo H20 from its place as our main lube.
