Seems to work well. Feels and looks cheap but functional. Its not a fluke but its good for the price. Serves its purpose.

It’s as described, the buttons for testing after the third use stuck in depressed state. I had to work the button to get unstuck. I hope I can get my moneys worth from tester.

I like being able to calibrate the needle and I like the adjustable voltage output. I had a 480v 3 phase motor that was tripping a vfd on a ground fault intermittently but would run no problem on bypass. I put this megger to it and it tested ok at 250v, very sketchy at 500v, and an apparent direct short to ground at 1000v. I was very impressed that a $200 meter was able to clearly show evidence of insulation break down. We had the motor redipped and replaced. The motor megged good at 1000v.I have been using this meter once a week for over a year now.

Works well. Needs alligator clips on both leads. Hot my own. Superior product.

Solid dependable device. Also goes up to 1000v, which many other competing devices do not do.

A real nice tool to have around when you are building high voltage battery packs for vehicles.

this is the coolest megger i have ever used! Easy, effective, I find shorting wires and bad motor leads with it effortlessly. THANKS!
