Loved the ease of use; like nail polish. What I hated was that after the first use, the top wouldn't open the next time I used it. I kept it upright the whole time to keep the glue from getting into the cap, but I don't think that will work. I tried to open it and it was sealed. I threw it away thinking maybe I just got a bad bottle but the second one was the same. I used it once and today I used it again and indeed it was glued on. That's a lot of money for one bet! Maybe they are damaged? I bought them at the supermarket and they work great.
