So impressed!! Handy features, great quality!
Excellent knockaround multimeter! The magnets on the back are a great touch and so useful! Previously bought an automatic multimeter for twice the price that was nowhere near as nice or useful. I say “knockaround” because I leave this on my bench where it takes more abuse and I can keep my more expensive multimeter tucked away to use remotely.

Works well for me
Auto-Ranging Digital Multimeter. I am more than pleased with this multimeter, it has everything I need. I will only buy an auto-ranging auto polarity multimeter and one that can test capacitors. I bought this because I could hardly hear the beep when checking continuity on my other one. This has a loud enough beep. It also has a magnet on the back which is handy.

Very good product.
Compact and well built, helpful for model train enthusiasts who need to check voltage and amperage with track and power supplies.

Satisfied So Far
Works at advertised, not much to say on the technical front. The measurements are acceptably accurate for a product in this price range, it looks well made and the use of standard batteries makes it pretty convenient.

Good meter
Grate works grate my back of orange cover missing the magnet I was willing to give 5 stars but missing a part I will not be returning the meter because of the magnet

Good value and measures capacitance

Creo que tiene una buena relación calidad-precio. Es más grande de lo que parece, por lo que la pantalla es más grande de lo que esperaba y es fácil de leer. Tiene muchas funciones. ¡El manual solo está en inglés!
