At the risk of sounding like a commercial, this stuff helps things fit together. The only down side is that you may need to reapply occasionally.

Highly recommended

Assuming it's for masturbation, this lube works well if you can get off fast. As in under 10 mins unless you start producing some of your own lube b/c it dries pretty quickly. I had to reapply several times for longer sessions if I wasn't lubricating myself.
The smell doesn't smell, but the taste is awful. It's this chemically foul taste that I hate. If you don't mind not tasting anything down there, then this lube will be fine, but look for another if your the oral type.
Obviously don't try this for anal penetration since it's too thin. It's slippery, but not water slippery. It feels like your very own lube.
Not bad for the price and it's quite a big bottle and yes, a little does go a long way.
Don't try applying more to make it stay slick longer, it won't work. You'll just be wasting it, instead apply just enough and reapply if needed.

This product is overrated, it's not slick enough, and dries too quickly. It also has a slight acidic smell. The only plus is its large size, but you'll go through it quick because it dries fast. Astroglide is much better.

this lube is definitly the best kind my boyfriend and i have tried. we love it!! The small two pack has been lasting us awhile.. a little goes a long way.

This is hands down ;) the best lube ever, for any activity.. does not get tacky..ever. Only con is the taste.
