Its very robust and high quality work. Once locked in, there is no way to escape. My mistress know, and forced me to spend the weekend with the head cage on.
This was my first time purchasing a product like this and was not disappointed. It is a little tricky to get in at first but one in it give a great feeling of fullness. Stays in place very well and is comfortable to wear around.
I love lub up, slide the sleeve on and play with the wand speeds while watching porn. I edge for hours sometimes allowing myself to cum, sometimes after dripping with precum I don't allow myself release which just added to the build up for next time!
