I have 6 different ones, 4 normal sized ones, ice speed bumb mouth, ultra tight butt, the original vag, and a vag super ribbed, and then 2 smaller "sex in a cans", the mini lotus, and the sukit... Of them all, the Sukit is the newest, just got it a couple weeks ago, and it is by far my favorite... My ratings from best to worst would be, Sukit, Super Ribbed, Ultra Tight Butt, Mini Lotus, Speed Bump Ice, and the Original... I learned the hard way though, that you have to be VERY careful with the Sukit and the end cap... I left it sealed the whole time I used it once, about 20 minutes, and there was soooo much suction that I actually popped some blood vessels in my dick, turned it purple, and it was engorged with blood like I had been pumping... Worried me for a bit, but everything went back to normal after a day or so, but yeah the Sukit is AMAZING....
