I will never be without this! I don't feel like all of my makeup is completely off unless I use this facial brush. It exfoliates really well, and overall my complexion looks so much more smooth and soft. I think I paid $30 for this, which is completely worth it - especially compared to other facial brushes like the clarisonic. I've tried the Pretika facial brush and I liked the concept of it oscillating as opposed to just spinning like the Olay Pro x... But the brush head on the Pretika was really big and it didn't feel like it ever got my skin all the way "clean" & it just quit working after like 2 months. Ive had my Olay pro x brush for about a year so far and ive had no problems :) Pretty much, this brush is amazing!
