USA SELLER _ HEPS Otris Construction System Cup by [ CoolMaleSexToy ]

It is a good idea, but I should have listened to the other reviewers. Once I received the package I really wanted to give it a go. I read all the instructions and constructed the rings to the way I wanted. Once ready it felt good at first (tight) and has really good suction (VERY LOUD). As time went on the inner rings began to collapse (really sucks) and lube started to leak form each to the rings fastening points (Messy). Once done, cleaning was okay because you unscrew and wash all the parts. However, cleaning was also a pain because you have to clean all the parts. For me this thing was a complete waste of $$. I think ones like fleshlight or sleeve based are tried and true!Good luck if you want to try, but at $70 it was an expensive experiment! ;-(

I am in LOVE with this thing. Everything about is just great. Close to the real thing I've gotta say. Only negative thing is that I'm not really big on is that it's a little bit on the small side. Other than that, overall it's just wonderful and a great piece to own.

Interesting concept, poor implementation.

HEPS Otris is very cool.The design and attention to detail of this toy really is spectacular. The hard plastic shell looks really good and is surprisingly functional. With all the ring selection you can build your favorite inner structure and affect your masturbation experience to the max!

Way too tight which made it virtually impossible to stroke, even with lots of lube.For the record I am not a 10lb. The inner soft pieces would come out of place. I tried with the lid off as the suction was too strong, no change. I have many toys and trust me when I say this is the worst. If you have a small unit then maybe it would work??? Maybe?I do recall the packaging saying it is novelty item, so there you have it. Also heps says the inner soft pieces are made from silicon and it is not, at all. Probably why it doesn't feel good

It's not that this isn't a great quality, high intensity masturbator. That's not why I'm giving it one star. If your big then you cannot fit inside this masturbator!!!!!!! I found this out the hard way (no punt intended)! The product doesn't specify up to what size girth it can accommodate! Beware!

Way too expensive for what it is. Just a soft plastic polymer that is encased in a hard plastic. There are many other options out there that are much more affordable and even feel much better!
