I found this to be of very cheap quality and manufacture. When checked against a calibrated fluke amp meter it was found to be wildly inaccurate. I could not be more disappointed in this product. I would not recommend this product at all. My advice is to pay extra and buy a fluke or another reputable brand and don’t waste your money on this garbage.

Just Great

It's difficult to get accurate readings with this thing. One thing I really don't like about it is that the on/off knob is raised above the top edge of the device, so when you put it away in its soft case, the knob hits the case and rotates to the "on" position, so it's in the case but turned on. It's good to see if you have current moving down a wire, but won't easily give you an accurate reading. Overall build quality is about 5-6/10

great product at the right price

This meter works great. I use it for checking my solar panels to insure each panel is pushing power to the inverters. Without this, I'd have to have someone watch the current output of the array and then cover each panel with a large piece of cardboard and see if the current drops by one panel's worth. That is easier than unplugging each of them, but just clipping this meter over on of their leads is WAY EASIER than anything. Now the hardest part of this testing is getting up on the roof and finding the wires. It is also a one-man-job now since I don't need anyone in the house at the inverters with a walkie-talkie.I do wish there was a way to turn off the current sensor. It is on 24/7 and flashes anytime the meter is bumped. Clearly this will wear the battery down and if it is not removed when it is dead will corrode the battery terminals and compartment.UPDATE 06/10/2015REALLY wish the current / voltage presence sensor could be turned off. I need to store the meter in a zip-loc bag with the batteries removed because otherwise it constantly flashes and will kill the batteries which will leak and ruin the meter. That is REALLY ANNOYING! I need to unscrew the back, insert the batteries, screw the back on, use the meter, unscrew the back, remove the batteries, screw the back on, and put the parts back in the zip-loc. This is not very convenient when you want to check something quick.Also, the DC current sensor gives two significantly different values if the meter is clipped on the wire 'forward' (giving a positive reading) or 'backward' (giving a negative reading). This makes me suspicious of the accuracy of the DC current readings. I used it last evening to check the current draw from a battery to an inverter that was running lights on a carnival booth my church was running at a local park. It registered +6.2 amps when clipped on the positive lead one way. It registered -4.8 amps when reversed on the same lead. I moved it around to see if the position of the lead in the clamp mattered or the angle, etc. Nothing seemed to affect the readings significantly and it was reproducible multiple times clipping and reversing. While packing up at the end of the night, the fellow helping me asked, "Why is your bag flashing a red light when I move it?" The meter was in a small nylon tool back and was flashing through the cloth when it was moved even gently. And there was no 'voltage' nearby to sense since I shut down the lights and inverter by that time. I had to explain how the voltage presence sensor on that meter cannot be turned off and I hadn't removed the batteries yet.It still works for the main use I have of being sure my solar panels, which are all connected in parallel, are all connected and pushing power to the charger/inverter. But I do not consider the readings to be accurate for the DC current.Added photo to show how I need to store it so that batteries won't die and leak inside the meter and corrode it all apart.
