Dr. Love Lube stands out among silicone lubes as being somewhat less thick than your average silicone based lube, though still more thick than water based lubes usually are. It doesn't require frequent re-application, though, which is nice in the heat of the moment.
Dr. Love Lube doesn't have a significant smell of any sort. It reminds me of all the other unscented lubes out there--not quite like any naturally occurring smell but not unappealing, either.
The most critical test, when I'm looking at a silicone based lube, is whether it passes the shower test. The shower test is actually not a check on whether this lube is good to play with in water--because it certainly is and is preferable to water based lubes in that respect--but rather whether I can wash it off after use. Success! Dr. Love Lube stays on while you want it there and comes off with some soap and water.
Dr. Love comes in a black cylinder with a great squirt top. Though the squirt top does require two hands, it gets points from me for having a double guarding mechanism against leaking lube. Not only can you turn the push part so it's in the off position and can't be pushed down accidentally in a toy bag, but it also has a cute little cap that snaps on!
