    Best amp/volt/capacity meter for the price?  Almost.
  

*by M***A on Reviewed in the United States on March 23, 2019*

So far this seems like a great meter.  *except* it gets out of calibration over time.  Needs to be reset (with 0A flowing through the sensor) from time to time to be useful.Some tips:1)  To calibrate the current to zero (when no load present), press and hold the bottom button for a few seconds.2) To extend wiring you need 4 wires instead of 5 -- the center wire in the sensor harness is ground.3) Make sure to install the hall sensor with the arrow pointing towards the load end.4) When programming options, the unit won't "remember" the settings if you don't confirm them by pressing and holding the top button.Edit: changing to 2 stars because it requires recalibration quite often (a few times a day if you want any accuracy) - which is a pain because I need to take all load off the battery to calibrate the amp meter.  If they fix this issue this meter would get 5 stars from me.

*by I***E on Reviewed in the United States on August 16, 2019*

I am using this for an automotive application.  Here's what I observed bench-testing the unit prior to installation -- indoors at room temperature:  Current draw, backlight off:  6.1 mA @ 14.0 V  Current draw, backlight on:  17.9 mA @ 14.0 V  Meter accuracy, voltage:  +/- 0.1 V, 0-15 V  Meter accuracy, current:  Unable to zero, unit always reads -0.1 A.  Meter reads up to ~10% low for positive (discharge) current, ~10% high for negative (charging) current, over the range of +/- 5A -- the limit of my bench supply.  The attached graph shows the current accuracy over this range.  I hope it performs this well in the vehicle.The limited precision and accuracy of this meter, even in a relatively low-noise lab environment, means that it won't be useful for tracking parasitic discharge or trickle charging on a parked car's battery, for example.  In fact, I would consider its current consumption on the high side for a continuously powered car accessory.  But, it should still provide interesting and useful information about the voltage and charge/discharge rate during vehicle operation.I successfully swapped the LEDs in mine to match the rest of the gauges on my dash (2 x 0603), and wired them to my car's dash illumination circuit.  This requires disassembly and rework.There is some sort of communications port (unpopulated) on the PCB, but I couldn't find any obvious access to the "alarm" signal for voltage too low.  So the alarm only flashes the display, which is pretty useless.  I wish they gave us access to the alarm signal, or other options for I/O.No comment yet on performance in-vehicle or reliability.

    Got the Meter, now how do I program it.
  

*by K***N on Reviewed in the United States on March 18, 2019*

Well, I was in the question mode, got the meter, now how in the world do I program it. The answer after looking around on the internet and reading all sorts of reviews, I found that Amazon support keeps PDF files for there devices they sell, was able to contact them via support texting and ask for the file I needed. Was no real hassle to get once I found my road blocks in my computer, a simple download and made a hard copy for future reference. Hope this helps someone else too.
