The best. I bought the tenga products from https://www.voluptas.ro/tenga
Original Vacuum CUP
I really loved this product
A friend bought me the USA cup as a gift, and I thought it was a bit too big to handle well, so I bought myself the smaller one. I'm only 6" but sort of thick. While the feeling is similar to the USA size, this one was a bit too small for me. Hard to get it in the hole. Once it's in, it's ok, but it's tight.
So I've tried this and the spinner shell. I prefer this. Only wish it was reusable.
Since I give the Premium cup 5 stars, I can only give the Original cup 4 stars. Great products from Tenga.
