My personal favourite is the Lilith Uterus (I have regular, hard, soft). I like the feeling of the 'cervix' at the tip, but I would ideally want a longer version. Basically I am poking through to the end all the time, instead it being a special thing.

The stats on TD are good, but inconsistent: for some products they have the length, some the tunnel length, some have pictures with superimposed rulers.... I presume this is because different manufacturers report things differently, not intended as a slag on TD. But it does make it difficult to compare.

Has anyone found anything longer with a cervix?

(that last sentence seems ridiculous, but I can't think of a better way to ask:)
