The high ratings on the Boss seem to be by looking at the can and feeling the weight in the hand. No one has a scale? From the cut open Red, not a lot has changed in the construction except the shiny paint. I know one thing, it is very doubtful the Boss equals the Fram Ultra they are taking from the shelves. First, plastic mesh is not stainless steel mesh, second where are the micron ratings, third have any been analyzed or even cut open?
