Bought set of two. In both the cap is assembled to the bottle incorrectly the nozzle of the trigger misaligned with the nozzle of the can so that nothing would spray. Was able to get it to work by prying the top off bending things back right again (the nozzle on the can is about to break off) and re-assembling but nobody should have to do that. Worked okay for a bit but with about half the weight left there was only a slight breeze coming from the nozzle. Look elsewhere.
We typically think of dusters for electronics but clearing the lint from quilting machines is critical. Accumulated lint and dust can clog and derail pulleys and gears on long-arm sewing machines. This duster works.
