As much as I saw a little improvement in my cat from using this, I wasn't willing to risk burning down my house. I received two diffusers and both started to smoke. When I took them out you could see that they were starting to burn around the plastic. Definitely a hazard and will look for other options.
This makes it really easy to learn to contour and be able to experiment where to contour. However, it is a really greasy formula especially if you already have oily skin. It also made my skin break out where it usually doesn't.
NOT shine control at all. My face was shiny within a few hours and had to keep wiping with a tissue. Pretty much defeated the purpose of trying to keep my makeup on with the primer. Would not recommend this for already oil skin. Will try to find another primer with a matte finish.
My kitty just loves this ball! It's a great way to get her to exercise and she will even play with it on her own. Tip: Scratch the ball with a knife or your fingernails every once in awhile to release more catnip.
