I own 3 fleshlights. Definitely worth the money, seriously. Destroya is the best insert that I've tried (with the Stoya mold to boot!).
I'd be more interested in Tenga if they weren't marketed as being disposable (even the one that you can clean allegedly has limited uses).
Protip: buy some rubbing alcohol and use it to clean your toy. Not just because it's super sanitary, but also because it dries extremely quickly, you don't have to worry about mildew and grossness.
Now, I'm REALLY interested in the Soloflesh. Definitely will get one eventually. Check that one out.
Don't be afraid of spending some money on this sort of thing. Unlike a lap dance, massage or hooker, masturbators amount to more than a single experience and cost the same. It is highly unlikely you will regret it.
