Without question, this is the best water lube I've tried. Tasteless, odorless, long-lasting, hypoallergenic, and paraben and glycerin free, this lube ROCKS. Other water lubes state that they have non-tacky formulas that don't stain, but this lube truly keeps on that promise. And it doesn't sting if things get rough, like other water lubes. Sliquid H20 is an excellent lube for any kind of play (and safe on toys of all kinds, too!). The only thing you'll have to worry about with this lube is running out.
