I was looking for product manufacturer on the web this morning. I found a few sites, but one was notable due to the PDF's available for download. That was good, since the engineering information was available.
I downloaded the information, which caused a few computer glitches due to the size of the files. I've had this happen before, but it's a minor inconvenience. Giving an engineer the information they need for product approval is a good thing.
So, I called the nearest sales office. It was disconnected. No problem, they probably moved and haven't updated their website. I tried the next to nearest; same thing; disconnected. Last option was to call corporate, which I did. I was rewarded with a recorded message asking me to refinance while the interest rates are low.
Long story short: I did a little research and found the company, which is a really big company, dropped this particular product. There was not enough money to be made, I guess. They do have a wonderful, useless web site.
