Just received 4 Microgard Select MSL57356 from O'Reilly, had to order them online so wasn't able to actually look at them. I had assumed (dangerous, I know) that these were made in Vietnam likely others that were cut/examined here on BITOG. Well, turns out they are made in China. I generally avoid Chinese products as they cheat so much. They SEEM well made, but I'm uneasy about using them. Should I just go ahead and use them? What's the experience here with Chinese Microgard Select filters?
