Good overall meter for occasional use. Sometimes in sunlight, the display will wash out, but so do most digital meters. Easy to use if you have ever used a VOM. Several features on the meter are yet to be explored. I purchased the meter to troubleshoot the CAN Hi network on my Volvo. The meter met the challenge.

Very nice meter. I did not everything I would use the NCV feature on this meter but had to change a tankless hot water heater and wanted to make sure that power was actually off. Just held the meter to the the wire going to the unit and verified it was off. No reason to use the leads. Also noticed this works with USB cords as well to see if they have power at the end. I also work on analog power supplies which will have large capacitors on them. This unit is able to measure these which my old meter would not. So far I am very pleased with this meter.

I am pretty happy with this multimeter, but there is room for improvement. First, the dang thing beeps every 10 or 15 minutes to remind you it's still on. The beep even occurs when you bypass the auto-off function! Second, the display is not as easy to read as other meters in this price range. I see a lot of reflection off the plastic lens, and the LCD display is not super bright. Lastly, there is a big chunk of plastic on the top of the backside that keeps the unit from lying flat. I suppose this is to accommodate the leads while in transit. MY unit stays on my bench.
