These bottles do the job I bought them for, but they definitely weren't my favorite vaporizers. I took off a few stars because I didn't like them. What I like about them: 1) The size is comfortable. Not too big, not too small. 2) They are black. If you're looking at black aerosol cans, you probably need them for light-sensitive applications. What I didn't like about them: 1) Spray nozzle on or off. No spray jet adjustment. Maybe I missed it in the description. 2) My arm hurts when I use them! The application I use it for usually requires spraying until the bottle is empty. Unfortunately this has resulted in a blister on the thumb where the atomizer head rests! I have to use them often enough for numbness to form. Once I find replacements, I move them to my Desperate Use Only container.
