First off, I own multiple Klein and Fluke testers. I still use these for multiple applications. Each of these cost in the excess of $ 100.00. I always need to remove their batteries so that the batteries don't leak and destroy the tool. It's a "best practice" thing.Here's the cool things about this tool, it's inexpensive and it doesn't take batteries. You plug into a socket, and it's powered automatically. I checked it for accuracy against both my Klein multimeter, Klein socket tester, and Fluke inductive testers. It was dead on for all measurements: Volts, Amps, Watts, etc.Here's the question: Why would I use this if I wave the other meters? Well. this is quick and easy, and I hate reinstalling batteries in each of the other devices.If I have multiple circuits to check or troubleshoot, I'll beak out the Klein and Fluke tools, but if I only have a couple of things to check or I didn't have multiple hundreds of dollars to spend, this tool is a very reasonable substitute.The only drawback that i can see, is that this tester resets back to W (watts) every time it's unplugged. It's a small annoyance to cycle to one of the other measurements. It only takes a few seconds, but it's an annoyance.Note: The directions are a little weak. To cycle what is being measured, you hold down the (M) button for about 5 seconds, the screen will flash, then tap the (M) button again until you see the proper field you want to be measured. It only takes a few seconds.I would definitely recommend this tool.

If you're curious about power consumption this is a handy little device. I've used it for space heaters, electric kettles, and various high wattage devices. It may not have a memory but it provides me with information I otherwise wouldn't have. For $10 I'm pretty impressed. It's well made with good fit and finish and it's easy to use. Now if I can just stop myself from measuring everything in the house! ;-) :-)

Alright, so I got myself one of these simple watt meters, and honestly, it's been such an eye-opener for understanding my electricity use! You just plug your appliance into it, then plug the meter into the wall, and it instantly shows you how much power (watts) it's drawing. I used it on everything from my gaming PC to my fridge, and it was fascinating to see the actual consumption. It's a super easy way to identify those sneaky power hogs in your home. If you're trying to be more energy-efficient or just curious about your gadgets' consumption, this little device is a must-have for basic energy auditing. Simple to use, and really useful for getting a handle on your bills!

Its simple, works well and has a great backlight for easy viewing. Just what I needed. Would recommend especially for the price.

Very easy to use. Good product for the price. I would be a repeat customer.

Working as expected.

This power meter is very basic. I measures watts, and also kWh, but it does not keep track of the amount of time it's been running. To get kWh per day, you'd have to plug it in and set a stopwatch, and after waiting, you have to calculate how many kWh per hour.There is a nicer model of this same meter that measures time, so I will be tossing this in the TRASH and getting that better one.
