Just wanted to give a shout out to Griffin Enterprises of Kalispell, MT. I like companies that stand by their products. Griffin is definitely one of them.
I use a 14-year old Griffin Superior 3ARP vise regularly. More than my other two vises. It's very dependable. But like anything else, it wears with lots of use. Man, have I used it. It's without a doubt the most versatile and useful vise that I own.
Recently, I cracked a small adjustment knob/screw on the vise jaws. I then contacted Griffin about it and now have a replacement for it just three days later. I wasn't charged for the part or its shipping. They've sent me o-ring replacements for my vise jaw assembly in the past too, free of charge.
Customer service lives. Griffin is a great company.
