System Jo H2O Anal and Maximus last about the same time (depending on where you put them-vaginally will last longer because they mix with natural fluids, anally will need reapplied after so long [perhaps 10 minutes or even longer depending on what you're using back there as in a silicone toy, penis, whatever]). Maximus is thicker and they both have parabens.
Simone Extra Slick outlasted both of those because it is indeed pretty slick, but it's rather thin and runny.
Bedroom Kandi is just Sliquid Organics Natural
, which was meh. Doesn't last too long and foams up. Same with Sliquid H2O. But I hate Sliquids lubes because I had reactions to them (weird burning that felt like someone poured hydrogen peroxide into my vagina and funky smell). I think it is the Potassium Sorbate that caused the reaction, so stay away from Sliquid if you think you might react to that.
I have not tried the V Ultra Sensitive because it has been out of stock for forever...but I have the Gel version of that in the mail, so I'll be trying it soon.
