I own both the autoblow ultra and the vacuglide 2 I was shopping for new sleeves and would like to know if anyone can comment on which is better and why between the contest winners pack(im going to get all 3 if I go that route), the riko, and the vacuglide made for pumping. I am pretty thick so some toys don’t work for me. I’ve had no problems so far with any of there products. Thanks to any one who takes the time to give me some advice, I really appreciate it.
