Well, a couple of months ago, Castle's customer service was the standard by which others were judged (that's the way I see it anyway). As of the last month or so, I've been having problems getting timely responses to emails and phone messages. I don't know what's up.

I do know a couple of people who have had problems with their MM systems, shortly after getting them, and they were sent new systems right away. I haven't had any such luck myself, but I haven't had a MM that I ran within spec either, so I've never been looking for warranty work.

If you do get a MM system, it is more than likely that you'll be satisfied with it. If you need warranty work, Castle has implemented a form system. You just fill out the form on the web, print it out, and send your stuff in with a copy of your receipt.

Other than that, I can't tell you anything more positive. I still like their stuff, but I am not as much of an avid Castle fan as I was a couple of months ago.
