I would say if you're going to get one, make sure you go to a specialty shop and make sure you talk to a sales person who knows her ♥♥♥♥.
its a damn shame, but vibrators/dildos are NOT regulated very well at all. they're usually manufactured for cheap, with questionable materials and paints. as a result you can wind up buying one that's made out of... not great stuff.
the hippie-dippier the shop, the better. the more expensive the piece, the better. for your own safety, (slash enjoyment) this should be an investment, so do the research into the materials or whatnot. :3
I don't need if you're planning to buy anything or something, but vibrators are too expensive these days (IMO). I actually suggest getting one of those smaller ones. Can't remember their name... I just call them "eggs". They're much more cheaper than a larger vibrator.
