I picked up a bottle of Diamond Dry Top Coat at Sally's a couple of weeks ago. They were having a deal- buy 2 China Glaze and receive a free Diamond Dry Top Coat. The first time I tried it, was on my toe nails. It dried nicely, no bubbles and VERY shiny. I loved how shiny it was. This was about 10 days ago and they are still shiny! I tried it a few days later on my nails. It was very shiny, but I had some drying issues. I noticed it didn't dry as fast as I thought it did on my toes and I smudged it pretty good on a few nails. It also didn't last as long as my favorites(Out the Door, Seche Vite, or Zoya). When it chipped, it was nig chips.
So, in my opinion, Diamond Dry gets bonus points for shinyness, but I am glad it was free and I definitely would
not pay the $7.99 price they want for it.
