The idea behind the sprayers is excellent, the usability is horrible. Takes an act of god to fill them without spilling your expensive hand sanitizer all over without a tiny funnel, then once filled, you get 1 maybe 2 uses out of it before the spray tip comes blasting off the end and you end up with a solid stream instead of a misting pattern. When the misting works, it's great, after that it's just garbage. Better off with the 4oz bottle with the pump style sprayer head. Bought the 6 pack and so far 3 have broke in the first use. Sorry Adam's, great idea, poor design.
