This is a very well-made toy. I was looking for something that I could start practicing DP with, I wanted something soft, and not too big, this seemed to fit all the criteria, and would be a great toy for that if it didn't have the Vac-U-lock hole in it.
I wasn't sure what that meant when I ordered, if you're the same, I'll explain. Doc Johnson has cored out the bottom half of the toy in order to be able to connect it to different mounts, many available on this site.
For me, what that means, is that you need to have a firm grip on the base of the toy, in order to slide it in with the other toy / partner.
On my end, the stretch is gentle enough due to the softness of the toy, and for my partner he says the same thing. He loves the tightness it gives, but with a bit of give so it's not uncomfortable.
I've played with other toys for this purpose that were firmer, and they weren't nearly as comfortable for either partner.
Overall, this toy feels great. Soft enough to be comfortable, firm enough for easy penetration, if you get it though, make sure you pick up a vac-u-lock base for easier penetration.
