Have not had time to use these. So far working as expected But very PRICY for 4 compressed cans. I could buy a bottle of Oxigene and breath better too.
I bought it to dust off the wheeler in the air conditioner. The very first spray shot was very strong and dusted off. Even wheeler was rotated by the spray. But from the second spray shot it made a sounds like a spray but never dusted off. Of course the wheeler did not move. I bought 2 cans. The second can had a same issue. I should have bought a 3M brand. Wasted money.
