Just for starters- THIS IS NOT INSERTABLE. I liked how inexpensive this toy is, and how cool it looks-I don't like how he doesn't grow as big as the package shows he will-But he's still a fun toy to play with never the less.He grows great in the water, though it took around 48 hours to get him to the size he is now (about 4 inches) and took at least 3 before I saw any change at all. When I took this out of the packaging it was about 2 inches long. Besides taking this out of the package and having fun watching it grow, and then squishing it between your fingers after it's enlarged, you really can't do much with this toy.

It's more of a gag Gift then anything else. When fully grown it has No real smell, and I didn't taste it since it doesn't say what it is made of and I don't want to risk possibly hurting my insides.. It feels nice, and when you squeeze it no water comes out (even if it does come to the surface) If you run your nail along this you end up with some of the material on your nail/finger (even if you just squeeze it hard, this happens) So that is a definite con for me.
Also, the balls end up looking a bit weird after they are grown.. more like a butt then balls.. kind of strange!!

It didn't seem to play a role in my sexual experience, though my and my Partner did have a fun time watching this grow and then playing with it afterwards. I really do wish this thing had grown to the size the packaging said, since that would make it a lot more fun. I'm not sure what material it is made of, since neither the package, website, or Edenfantasys tells me what it is made of..Since I do not know the material, if this gets dirty I recommend letting it either sit in water (and therefor grow again!) Or rinsing it off with water. At it's smallest size this could be taken with you for travel, or given as a gift for somebody with a lot of humor!

This is still quite fun. I left it in the water for a week, and it grew even more.. It's almost the size of my hand. If you want it to get REALLY big, then leave it in there for a week or two. It gets huge!!!
