I was so excited to give this a try. I had gotten a Tenga Egg and enjoyed it immensely. I rather hoped this would provide a similar level of pleasure, but be reusable. This is much bulkier than the egg, but I still enjoyed it. Sadly, mine developed a small tear right at the entrance during my very first use. And I am not particularly thick - when erect my penis is only about 1 inch in diameter.
Maybe I got a defective one, but be careful!
