"Our line was down and we needed to get repaired fast. The fact that MEC is located in Quebec, Canada, it saved us from sending our spindle overseas. We were up and running in a couple of weeks instead of a few months. We saved time and money!"

— Robert Deshautels
"We were missing a part to repair our spindle and we couldn`t find it. We called MEC and they machined for us from scratch. Their technician was a big help and spent hours on our problem. Great Canadian company!."
