I got leaking inside the cap, but it didn't come out.
This is a nice spray bottle kit, it comes with 2 funnels and a sheet of labels, I found the labels too small for use, each one is approximately 1 inch x 1/2 inch in diameter, and not sure if it can be used in an inkjet printer or not. All 10 spray bottles included all the necessary parts, and the stem that draws up liquid was long in each one, none were short and I really appreciated that. You should be able to spray down to the last drop.  I tested mine with rubbing alcohol, for sanitizing my phones. The funnel came in handy for filling the bottle. It made the job so easy! The sprayer does spray a very fine mist. I used it several times to clean some things then left it overnight with the cap on. Next day I tested it again. First off, the cap contained some of the rubbing alcohol inside it, which means the container will leak into the cap standing up. Not necessarily a huge deal breaker, but a negative for me. Holding it in my hand I got the rubbing alcohol on my finger too, so this may waste product just from this. Several drops every 24 hours may not seem like a lot, but if you make your own essential oil room spray then this could be an expensive waste. Lastly, I had an issue with the spray top, the angle is so slight I wasn't sure if I would spray myself in the face of I wasn't wearing eyeglasses. You have to be careful, ensuring you're spraying away from yourself. I did not get any leakage of the alcohol out of the cap, it seemed pretty tight.  It did pool in the cap, didn't run down the bottle.  I did get a rubbing alcohol ring when I set down the cap on my coffee table tho.  Beware of that possibility whatever you use in these bottles.<br />All in all, a nice kit and I give it 4 stars.
