The initial feeling was incredible! Instant arousal. It fills you up nice and it stays in place. Very comfortable to wear for long periods. A bit difficult to insert, as the material is soft and flexible, but the metal ball helps. Insert with the inflation needle attached, give it a pump or two, and wow. Remove the needle and walk, sit or dance in relative comfort.
However, this is not a one person operation! While you can get it in yourself, it is near impossible to get out by yourself! First, you have to find the hole for the needle without poking yourself - challenging, but doable. Then, you have to insert the needle far enough todeflate the device. However, the arms are so flimsy, just the force of pushing the needle in can cause the whole thing to fall in! You need another hand to pull on the device while you push in the needle. I had a moment of panic and visions of people trying to awkwardly explain their situation to spouses or medical personnel. Do not inflate more than a pump or two until you are very comfortable you can remove it and/or deflate it by yourself (the more you pump, the more it tries to pull itself deeper.) It deserves five stars, but not if you can't get it out! Needs a much firmer base to be used by one person.
After removal, there is an odd feeling of it still being there. I assume internal stretching? Probably not something your doctor would recommend. But, it feels really great before the panic sets in! :)
