It's really nice. There's not too much in the bottle though... just maybe 1 teaspoon worth. It's REALLY nice though. It is kinda like a vaselinish feel, smooth and all that,but doesn't get gooey (if you know what I mean) and it doesn't ruin the plastic. The lube comes out in drops, so you won't waste it. Trouble is shipping. The price actually includes shipping; the stuff is really worth like 1$ maximum. I personally got a megaminx and lube came with it. You can do the same for some DIY kit I think...
It works really well on cubes, especially eastshean. But don't overlube, or else...
