I've actually had like 4 or 5 fleshlights over the last...erm...4 or 5 years or so? They had a menage trois deal ( 3 for 1) a few years ago.
The first one I got (s.o bought it) was the wonderwave. It's the one that most resembles the feeling of a real vagina. If you put it in warm water for 10 mins like they suggest before hand and then use a generous amount of lube it comes surprinsingly close to the real thing. It has the warm and gushy feeling and the right amount of friction.
In the 3 for 1 deal, I got a "butt" fleshlight, the one for Misty Stone. It was awful. Felt nothing like the real thing. Too smooth and slippery. Only used it once and I think I threw it away when we moved.
I also got a "stoya destroya" in the deal, since it was the highest rated one. That insert was prolly the most intense orgasm ever, but that's not necessarily a good thing. It was way too intense, so much that I could barely enjoy the release. I used it for about a month or so just cuz the intensity was so foreign, like little licks and massages all over my penis, but once the novelty wore off I realized it was way too much feeling.
I forgot the other one I had. I'd have to go to the site to see, but I didn't use it much. I have a wonderwave now in the closet but I haven't used it in a few months. It's a great toy but prep and cleanup got too tiresome.
