I also picked up the waterproof option, which again, was also quite wet. I gave that another two days, and it made a significant difference. It was great for a whole week, every day. However...after that first week...it was dried out to the point nothing would come out on the brush but a clump or two. So either there's VERY little in there, or that tube is not airtight...I can usually got 4 months unless I am piling it on before I need to toss a mascara.
The brushes are both very nice, large, and very plush. They left my lashes looking awesome, no clumping, and the carbon black was a great shade of rich black. It was VERY waterproof, in a good way. I didn't worry about rubbing my eyes either. It stayed.
However..for $7 or whatever I paid for each one...the waterproof can not be worthless that quickly. I had to toss it a week later and that's not going to fly with me!
