Some people may avoid System JO H2O because of some of its less desirable ingredients, but I come back again and again for its durability, thickness, and natural feel. A great substitute for silicone lubricant (which is incompatible with toys made of silicone), I'd recommend this product to anyone looking for a natural-feeling (if not all-natural) addition to their sex life.
The most helpful critical review
Unfortunately, our feelings toward H20 are not the nicest. For someone who enjoys more of a thick drag during play, rather than a slick surface, this might be your BFF. I for one, will never use it again. If you're a fan of Liquid Silk, this will not measure up and if you're looking for a water based lubricant that acts as a silicone, look elsewhere. Perhaps Pink would be a better option for that.
