I haven't gotten to try silicone based lubes, some of my toys are silicone so I only buy water based. I don't want the silicone toys getting ruined by anything. Though I do hear silicone lubes last longer, also hear they are harder to clean so I probably wouldn't like them very much.
I stay w/ waterbased lubes since I have so many silicone toys & I don't want to have to go through guess work or rely on my wandering memory. using a silicone lube w/ a silicone toy can cause the toys silicone surface to breakdown. and I don't want to lose any of my treasures.
