Haha! Yes I have! I have tried the ZXY and the Sarah. Honestly in my opinion, meikis blow fleshlights right out of the water. It is rather unfair to compare them in reality. I have not tried the Maria Ozawa so I would not be able to tell you anything about that one. My fav is the ZXY and seemingly from Toydemon that sells them, ZXY is the best one. However, they are just as pricey as Fleshlights, so that would explain my lack of meikis that I have experienced.
As a matter of fact I used the ZXY so much that I wore it out and bought the Sarah when it came out, however, the Sarah began to give me some kind of rash after extended use. Maybe an allergy?
Unlike fleshlight, meikis actually design the interior from the vaginal interior of a woman. Well... that is what I understood. I am not sure about you, but I do not see how that would compare to the fleshlights plethora of strange interior (ie. lotus) textures. All i all, the meikis are just as soft as the fleshlights, but actually feel real!
Mind you, I tried the lotus texture since it seemed the most attractive to me at the time, and in all honestly, I actually got bored during my session with it. Imagine that.
I guess to put it to you concisely, since FL and meiki are both soft and about the same in price, my question to you would be: Would you rather masturbate with an artificial tube (FL), or a replica of the interior of a woman's vagina (Meiki)?

Of course I am only one person and many people swear by fleshlight so if you have the money, try both. It is a shame that Edenfantasy does not carry meiki though.

Let me know if you have any more questions.

You could recommend the Meiki ZXY in the Eden Should Carry thread.

I have made some recommendations before but it definitely needs some more support in the forum . Or you can create a ticket and ask them directly.
