A useful device. It measures all its loads. The quality is good, there are no shortcomings.

I like this item. It showed me all the items that were eating electricity. Some big surprises. Excellent item.

It is wintertime and I have brought in my plants from outdoor. I was curious to know how much electricity my planting lights are using in order to maintain growth.

It's a fun gizmo to have around the house. I don't really have a "need" for it but it is nice to check and see how much power things are actually using.

You may have to be an amateur sleuth to really appreciate this little meter, but once you do catch on it will become an addiction! You will be able to answer questions that very few people ever ask such as How many amps is that toaster pulling, anyway?

I bought this it determines exactly how much wattage and amperage my pellet stove was using so I could build an adequate battery back-up for it to use during our ever more frequent power outages here in Northern CA. This gave me exactly the information I needed during all phases of my stove use from start-up to steady run on low to high. It's easy to use and easy to set up. Put in your price per kilowatt and it will tell you how much an appliance is costing you. Very handy and can't beat the price.

I cannot relay that this item is accurate, but it meets my expectation for my basic home needs. You don't need a certified calibrated equipment for home use. If you do, you are looking at the wrong place. I purchased this to verify the number of watts my computer uses so when I purchase a GPU, I can make sure it meets the limit of my power supply.

It's easy to figure out what the big users are at home, but this really helps weed out the unexpected power suckers.

I would say, for the price this thing is pretty great. My sole use for this is to figure out how much electricity all of my appliances use. It did it well and I can verify that I am getting readings stating what the manufacture states the max power usage is, so therefore I can trust that is accurate and not just pulling a number out of nowhere.

I bought this product for my mining rig. I connected the whole mining rig electric point to this energy meter and it shows the wattage accurately. I'm pretty happy with the product. Buy this device with confidence.
