I actually own one as well, but I have the Maria Ozawa Meiki that I bought a year ago. At first use I thought it was too lose to give me any sensation but after the 2nd and 3rd try the feeling was simply amazing. It is suppose to give you a slow buildup of entering a real vagina , the plus of this toy unlike the fleshlight is that it has a very complicated canal of rigids of bumps that feels better the deeper you enter. It's one of the best sex toy I ever used, I'm looking to get the new Rola Misaki version that is based on popular Eurasian starlet like Maria. The only place I found that sells in the US is a site call
