Great quality sprayer. Unfortunately, the plastic, chemical proof tubing for the wand was creased in the package, and ended up corroding through at those points when used with solvent-based penetrating driveway sealer after about 10 gal. No worries, quick trip to hardware store to buy better--MORE chemical resistant tubing did the trick. Nice gauage, well made. Only minor criticism is the spray actuator lock doesn't have a spring and gets engaged when you don't intend, resulting in continuous spray until you deliberately disengage it; a minor inconvenience. Still a great sprayer.
