I received a Canadian Tire Mastercraft grinder as a (X-mas/2008) gift from my mother. I used it once for five minutes to trim a wooden door. It was then stored with my other power tools. Recently I needed to grind a piece of steel plate. After grinding for less than a minute, a large washer fell on my workdesk and the disc began to wobble. (Front bearing failed.) I returned the grinder to Crappy Tire and was told that the three year warranty was VOID because I didn't have a receipt. I didn't want a refund, I wanted a replacement grinder. Crappy Tire here in Sydney refused to help except to give me a toll free telephone number for Mastercraft, their brand. I received less help from them, I was speaking with a very rude woman who couldn't care less about my grinder if I didn't have the receipt. My mother, the original purchaser does not still have the receipt but does remember that the grinder cost $59.99 + taxes. I feel "ripped off" and will never purchase another item from Crappy again my lifetime.
