IMO and now this is just my opinion so no one get their feathers ruffled. For non mechanical stuff their fine but for electrical and mechanical stuff I usually pass on Harbor Freight. I usually by from here with the mentality that this is "through away" stuff. Example I had to spray some POR 15 ,nasty stuff, so I bought a 15 dollar sprayer instead of using my 80 sprayer that would of took me a while to clean up.
