Bests & Worsts Reviews from Amazon

I failed to check all functions on my new meter when I got it. I had occasion to use the DC Voltage after about 6 months. It read 53 volts on a car battery. A AA battery reads over 8 volts, and a few millivolts with the leads reversed. Amazon supplied me with the contact info for the manufacturer, and said that it was up to the mfgr to resolve the issue. I have been waiting for a reply from them for over three weeks. If you buy from Mastech, make sure you check all ranges immediately.. Sinometer AC/DC Auto/Manual Range Digital Multimeter, MS8268
