good tool
Ok. So... this thing works great. seems to be pretty accurate. The only thing i know of is you have to make sure you firmly press the leads into the meter. Secondly, and may not really be a problem in most situations, is the read time. The amount of readings it takes in a set amount of time. So compared to my Snap On meter, this thing reads slow. This isn't an issue for me really. I have different meters used for different things. this one works great for testing out electrical systems without having to disconnect anything. Overall, a great tool for the money

Works great, reasonably accurate, good value
The product team that designed this meter did a good job. Feels solid, display is easy to read, controls are self explanatory. AD/DC voltage readings are very accurate, comparing with my lab-grade meters. Capacitance is -1% from my Fluke 117 - that's good. AC current readings are within spec, based on measuring HVAC heat strip current against known ratings. Certainly accurate enough for diagnosing motors, heaters, etc. I'd buy it again.

Good meter works fine
Seems to work fine so far. Haven’t used it much but when I did it worked fine. I would have preferred an Ideal or comparable but this one is fine for my purposes.

Good accuracy on DC Volts and DC Amps. Clear display in bright light or darkness!
I have two other clamp on ammeters. I needed a third DC Amps meter to allow measuring different wires at the same time. One of my other meters was designed with a reverse LCD display that has white numbers on a black background. That device was completely useless outdoors, where sunlight makes the readings on the display invisible. I decided to buy this MESTEK meter to replace the useless device and I was surprised at how much better MESTEK meter is. My calibration results against an Analog Devices DC Voltage Reference: 0.000V 0.000V 2.500V 2.500V 5.000V 5.010V 7.500V 7.49V 10.000V 9.99V Excellent DC accuracy! I used an inexpensive DVM with at 20 Amp internal current shunt to check the DC current clamp accuracy. 0.0 A 0.1 A 2.0 A 2.0 A 4.0 A 3.9 A 5.0 A 5.0 A Excellent DC current for an inductive clamp meter at this reasonable price point. Of course, these results are only possible if you learn to use the ZERO function before each reading. Clamp sensors are all subject to drift and offset errors. I have never seen a DC clamp Ammeter respond with errors of just 0.1 Amps in this test. This kind of performance would normally be associated with very expensive calibrated equipment from a big name manufacturer. User mode setting is easy, operation is intuitive, display is vastly superior to the other products with reverse LCD numbers. I must admit I am impressed at the good value this meter delivers.

Life saver!
The price for this meter was great! I needed to troubleshoot the electric brakes on my trailer. It was recommended to cut into the wires to each brake to perform the tests. With this meter I did not have to cut the wires. Cut wires and reconnects usually lead to future failures. With a set voltage applied I could see if the brake was drawing the current that it should be. I checked the meter voltage readings against my other meter. It performed well. I checked the current portion by using ohms law. It did well there also. Great meter for a clamp on dc current tester.

Unreliable
I bought this multimeter for the first time about six months ago, and it started freezing, making it unusable. I figured I just got unlucky, so I bought another one a couple of months ago — and today it started freezing too. The multimeter is convenient and has all the features I need, but it’s just too unreliable for field work.
