System Jo H2O is a thick, long-lasting water-based lube with great longevity. The feeling is very slippery, and provides some cushioning between surfaces, so it could be used for anal, as well as vaginal and all external lubrication needs. It also has a mild sweetness, with a light fruit taste and scent that reminds me of strawberry-kiwi, or melon, with no unpleasant aftertaste. This means it could be used for oral, for those who dislike strong sweetness or flavor. It cleans up easily with just water, although it absorbs so well without stickiness that I find I don't really need to.
The bottle isn't the most discreet, with personal lubricant in large letters on the side. The top opens and closes easily, and the thick formula makes it harder to spill in the heat of the moment. Now, my only real issue with this product is its formula, which includes both glycerin, and parabens. Aside from this, this is my current favorite lube, and if this company makes a version without these ingredients, I'll snap it up in a heartbeat.
