In theory, this was a great idea. I used to have an atomizer about a decade ago and loved it but it was a pain to refill. So I stopped using it. However, this one leaked on my first fill. I thought I just spilled while filling it, but sure enough after sealing it and wiping away any "spills", I turned it upside down and it just kept dripping right between the glass and the metal. Maybe it was a bum one, but it doesn't make me think too highly of their quality control. The atomizer I had 10 years ago was from a local drugstore for about a third of the price and it never leaked...just a pain to refill.
