Have received this product today. Power button missing and floating somewhere inside the body. Screen died whilst still calibrating with 6S attached. Sorry - utter rubbish at this price!

The quality isn't great, but for the price it's okay. HK needs to check before shipping because mine arrived without the little blue button. It had come apart inside. The button was obviously glued to something to allow it to reach the pcb mounted switch on the circuit board. Luckily the enclosure pops apart easily and I made up a new button and fixed it. Once the unit is calibrated I think the readings are pretty close but obviously this is not a precision instrument.

Very nice. Bought this specifically to measure the power usage on my H.A.L. hex. It's very light and not an issue for the hex. Stores max values so you can check them when you land.

Love this unit. I have this on my PSU to make sure I dont go over in Amps with 3 chargers connected to it. So far I have it at 18v and up to 45A for over 1hr. A perfect addition to a charge station

Good: Small and handy meter. Pointed correct voltage and current with 12 V input.

Bad: 'Hold' button is too deep in the case to use with fingers. If push it with a tool tip the button tends to jam itself down.

When first time tested it with 40 V input the meter died. So at least my example did not live nearly up to the specified 50 V input.

Could not test with high current because the meter was so short lived.

Great little item. I use this for setting up motors/props/esc's/battery combinations. A must if you want to avoid overloading and destroying your equipment.

The watt meter read the voltage of my battery as 12.75 when actually it was 12.48. I did a manual calibration and did a test run of the motor. When the test finished, it again went off mark. The display is also flimsy. I suggest adding $10 and getting the Watts up meter instead, which has pretty good reviews.

Good product works as advertised.I make use of the small size and lower(hopefully more accurate) current readings to make a special small motor meter by soldering mini(red) JST plugs to the shortened leads.Very useful for setting up Park and indoor flyers with correct prop etc.I obviously have other meters for normal applications.
