Hear, hear sister! I don't get it either...supposedly each one has a slightly different style of ribbing on the inside.

My guess is it's the same difference as there is between all realistic dildos of one material (like all cyberskin realistic dildos).

The inner textures are different on different models.

As there are hundreds of different dildos, ranging from very different to very similar, there are lots of fleshlights, which can be nearly identical to completely different.

I'm assuming your talking about the FLG series and each has a different signature internal texture in addition to the standard lotus texture, some aren't to different from each other, while other are like night and day different from each other. Owning several yes you can differentially tell the difference between the internal textures.

I think what may be confusing you is that EF doesn't carry the signature internal textures just the lotus model so it looks like they are all the same.

They really are different than other similar products

Yes, there are differences! The internal texture is the major difference with most of them. The external features, like the case, style of the orifice (usually a pussy, ass, or mouth), and the color are mostly cosmetic. One exception is the new Crystal series which has a clear case and a translucent sleeve that you can see through - which can be really hot for some people. There are also different types of Fleshlight styles - light their "Sex-in-a-Can" series which are usually a bit tighter and for small to average sized men.

Good point about there being a million dildos... are they all the same? Sort of... LOL
