As novel as the concept is, the cooling sensation is a nice little feeling while masturbating. On the bonus side, the sensation of heat when using it internally is an even better sensation. Silky and smooth, this water-based lube is great for those starting out, and it's temperature-altering nature also makes it a great item for beginners who are just starting out in the realm of playing with fire and ice.

Overall, like I said, it is a good water-based lubricant. I liked the packaging, as the nozzle type tip is easy for application. I did not like that it advertised a cooling and tingling effect, as I got little to none of that benefit from it.

I do think this product would work okay as a sleeve enhancer as it claims to be. But outside of that it wouldn't be worth the purchase. My partner's exact words were, "If I were to use this to masturbate alone, I'd probably need the whole tube." It really didn't last long enough for manual stimulation at all. And as someone who generally likes intense sensations during foreplay or sex, It was too intense initially for me and then quickly lost it's sensation once we moved on to intercourse.

Zero Tolerance Cool Masturbator Lube is a water-based, glycerin-free lubricant that can be applied to a masturbator sleeve, toy, or directly to genitals for a cool, tingly sensation. Those who enjoy extra wetness and extra pleasure will love this lube!

This lube is the best way to relax after a long day. It's better than just your average lube; it adds a cooling, soothing, and silky smooth feel to every use.
