We were very close to converting over to MET, but at the last minute decided to hold off. The deal breaker really boiled down to the cost of the labels. UL provides labels at pennies on the dollar compared to MET. Even if you outsource your labels locally, the cost is far greater than what UL charges per label. The first year would actually have cost us more with MET. Subsequent years would have been close to a wash. All other aspects of the program seemed to be fine. If they could get the cost of their labels down close to what UL charges, it would be a good deal.
