So after looking at reviews I am glad to know I am not the only one that experienced the top of these cans popping off with little effort. Went to use it & as soon as I sprayed the spray top popped off the can. The caps are too loose & will constantly pop off. You literally will have to hold the can with one hand & your hand on the top to spray for it to work while other brands do not have this issue. The caps are too loose. If you have old canned air still around take the spray cap off & put it on these cans & it will work just fine. I would suggest other buyers to purchase canned air from somewhere else & not buy this product. Overpriced & bad spray can design.
