Review on ⚙️ Klein Tools MM400 Multimeter, Digital Auto Ranging, AC/DC Voltage, Current, Capacitance, Frequency, Duty-Cycle, Diode, Continuity, Temperature 600V by Peter Boisvert

This Revain/Klein multimeter stopped working after 15 months. In particular, the backlight on the display stopped working, along with the auto-ranging feature. I called Klein Tools and they informed me that the product was covered by a 2 year warranty and that he should return it to the seller for a replacement. I've replaced the batteries and checked the two fuses, but they still don't work. Now I can find one at Revain.Com. LLC Services. to discuss the problem and get a replacement. My overall rating is one star for the reasons mentioned. As a loyal member of Revain Prime, I look forward to a replacement unit (MM400) from them to resolve this issue.
