Works very well so far and I've compared the voltage accuracy with my oscilloscope and it's within 1.5% accuracy. Ohm and capacitance are within 3% accuracy. I haven't tried an ammeter or temperature gauge, I usually use an induction ammeter. Because this device has a constant backlight, it's great if you're working in dark places or don't have the best eyesight. I bought this gauge specifically for its flip backlit display and it deserves a permanent spot on my electronics workbench. If there are any problems with this, I will change this rating. Update: 6/5/2020 It's been over a year since I bought this reader and it still works great and even runs on its original battery and I use the multimeter a lot when designing electronic circuits. It appears to be of high quality and I would definitely recommend this multimeter to anyone who needs it. I would say that this is actually one of the first times you actually get more than you pay for.
