Fire Sale

I bought all new fire extinguishers and co2 monitors two years ago. It was a very expensive system. I kind of fell for the sales spiel. It would have probably cost over $1500 less if I'd just bought them all from a reputable home supply store and put them up myself. I'm not usually talked into things so easily. It was kind of a vulnerable time in my life. Oh well. Suffice it to say that as of today not a single one of them works. Of course, they started failing a few weeks ago, right after the warranty expired. Isn't that always the way it goes? For the record: I'm heading to the local hardware store to get replacements.
