My rusty $5 harbor freight scraper actually makes crisper folds than that folder ever did.

I used to think those little measuring tricks were dumb and you should just trust the paperwork, but honestly this is genius. Sometimes the simplest tool is the one that finally gets through to someone.

Is it really that big of a deal though? I mean, you still got smoke out of your garage, right? Those portable units are hit or miss, but sometimes people expect way too much from them. The box fan trick has been around forever for a reason, it just works. Maybe you just got a lemon, or maybe the hype got you, but I wouldn't lose sleep over it.
