I bought it mainly to see how many Watts my computer draws and it shows correct numbers with an update every 1 second.

However, before the screen shows anything, it needs to be plugged into a socket and left for about 5 minutes so that its internal battery can charge. After that, everything is clear and the settings are very easy as long as you take a look at the instruction leaflet included in the box.

Sturdy construction, easy adjustment and smooth operation. I would like the screen to light up so you can check the consumption in dark places, but the absence of this function does not cause any problem. I think it is an excellent choice for its price.

At first, it might be a bit difficult for you with its settings. If you read its instructions carefully, you won't have a problem.

Purchased for €13, very high quality. It has a variety of measurements and very good accuracy. It also works on an inverter with "modified sine wave." If its battery runs out it doesn't turn on, but it can recharge when plugged into the socket.

Initially, everything was fine. Reading the other reviews, I left it permanently plugged into a socket so that its battery wouldn't discharge and die. Unfortunately, the trick didn't work... its battery (a cylindrical NiMH stuck to the circuit) gave out about three months later, with visible signs of oxidation... the cost of the battery (if you can find it online) is close to the cost of the device itself, so it's not worth it.

What a pity. While it worked, it was extremely handy and useful as a device, it really opens your eyes. Unfortunately, it is a disposable item...

P.S. To open the device (if you're curious) you might struggle, it has screws with a triangular head, but with a bit of experimenting you can unscrew them with an Allen or Torx.

Nice helpful tool, you see what your devices are really pulling; if it had internal lighting it would be perfect, you can set what you want to see

Flawless product, works with precision.

Very good, it has detailed indications and measures total consumption, both at that moment and if you want, you can set a price and it will give you the total amount for that specific socket and everything connected to it.

Everything is fine with the measurements (apparently). However, there is a problem with the time measurement, as if the clock is sticking and counting fewer hours.

Good power consumption and cost meter, I have it from another company and it is exactly the same, only the brand changes obviously it is a fake and they change the brand, the buttons are blue and not green as shown on the site, congratulations to skroutz for their quick response in correcting the photo

It's great in its measurements! I reduced my electricity bill from small changes I made based on this!

I used it for a few months, then I unplugged it and when I picked it up again after a year, it no longer worked.

I have been using this particular meter for quite some time! Immediate consumption monitoring and easy calculation! More details in the following video!

Very good construction and does what it promises. If the screen lit up when, for example, you pressed a button, it would be super.

Good price. User-friendly, no need for special settings. Accurate measurements. The only thing I would like is instructions in Greek because I bought it for my father and I had to translate it for him to be able to adjust it.

I bought it to see how much the heater consumes. Very easy "programming" of the kilowatt-hour price. (then I also tried it on other devices, out of interest)
- The screen shows the elapsed time, the current consumption in the main part of the screen, and the cost below. It remembers the data even when unplugged and continues when reactivated. You can reset it to zero.
- There is the option to see other indicators (amperes, etc.) but I didn't bother.
- I think the only downside was that there were no instructions in Greek, only in English and German.
- I would buy it again, very good for its price.
