There have been many posts complaining of MTH repair service time. So here's my recent experience. On June 23 of this year I sent to MTH a loco for warranty repair and a very old DCS remote that my grandson had dropped onto concrete, resulting in a blue screen. I authorized MTH to proceed with the remote repairs up to a stated dollar limit; it was not exceeded so they didn't call me before doing the repairs.
Yesterday I received a phone call from MTH saying that both had been repaired and requesting a credit card number to charge for the repairs to the remote.
To me, that is a satisfactory turn-around.
