I have been using this AC plug-in meter since 2009 and I guess I left it laying on a tree stump somewhere... This was a great analog meter as it had the scale painted up showing the safe zone.
I ordered the DM55-1 to replace it and it has been doing a great job as well. The only thing I don't like about it is the back light for the digital readout is very bright to me...
I order everything from AMAZON
