they're good for in-water play. they can be good for anal play. they're generally condom-safe.
however they're not good for use with silicone toys (like dissolves like). and they are too difficult to wash out of vaginas, so water-based is generally better for day-to-day actiities.
oh, and they're not good for oral sex, which is funny since i once got a batch of flavored condoms from Planned Parenthood that were lubed with silicone.
