Judging by your review of Rina and Roa, I don't think Lolinco is anything similar to Roa at all.
I have Rina and Lolinco and they are worlds apart already.
Lolinco is even tighter than Virgin Age ~Admission~ and offers far more simulation while it's at it. I would very much NOT recommend it if your member is on the upper side of the average scale or even bigger as you will most likely be liable to either hurt yourself badly or simply rip it apart (but judging by how strong it grips you, I would almost bet on Lolinco breaking you before breaking when talking inner structure).
Unfortunately I can't say anything about durability on it yet as it only arrived for me today but it's already on top of the list of my favorite little toys that I will most likely not be able to enjoy as often as I want due to the stiffness it demands.
I could note that I AM pretty new at the whole onahole thing and only got my first ones (two) a few weeks ago and got a few more today for experimenting and because I have nothing better to waste money on currently.
If people are interested, I can make reviews of; Virgin Age ~Admission~, Girl in the Box, Puni Virgin, Open My Pussy Lolinco & Rina, Tubomi, Smooth & Flat Girl's Laboratory. However I don't think I need to write reviews for the ones AkaiHebi already has, they feel quite accurate to my own experience.
