Did work for my use but didn't to a level of standard I enjoy with another more expensive manufacture. The company selling these is good, packaged well and no problems. Intended to use with 99.9% alcohol to clean automotive brakes that use piston seals not safe for the "normal brake cleaners" and electronic circuit boards. It sprays nicely not much dribbling after spraying has stopped. A nice handy size. Negative: This (mine) sprayer cannot hold pressure for hours without leaking, see picture. There is no "manual" pressure relief, so you must loosen the lid/pump assy to release pressure before storage, always a chance of contamination or spillage. I have other sprayers that have a valve for this reason but are at a higher price point, see picture -white part.I will be keeping it for indoor plant watering. It's good within it's price point.
