Purchase 4/07/2023 Calculate...
According to your comments, mine neither melted nor had any issues.
It works perfectly as if I bought it yesterday.
So don't spread negativity here.
People read comments to see if it's worth it.
And Yes!!! It's worth it

It does not have good accuracy, measured with a home clock. Also, terrible screen, you practically can't see at an angle

For the job I ordered it for, it's excellent. I wanted to see the consumption of the air conditioners to decide if it's worth replacing them with inverters. In the end, they consume 30-40% more than an inverter, but the reliability of Mitsubishi made in Thailand and Fujitsu made in Japan, which I have had for 25 years without any problems, made me keep them and not proceed with their replacement.

I have bought 3. I used them for 2 winters alternately. Measurements are correct with a small deviation. The display is average and gradually weakens, but you should know that after 9-12 months they "self-destruct." I mean that they no longer measure correctly, the instant measurement stops, and in general, they do not measure correctly; all 3 meters experienced this, so we are talking about a meter with an expiration date. It should be noted that they are not from the same batch, they were purchased separately

I bought two meters, both of them worked for about six months but their plastic had started to melt.

+ It has very reliable measurements
- Unacceptable screen
- Burned out within six months and after minimal measurements
If you don't get a bad piece, it's worth it because you learn a lot about consumption!

Very good. I have it for 2 months and it does what it says. You can leave it on any device for an hour and measure how much it consumes or constantly on one (e.g. heater) to see how much you burned all winter (if you don't unplug it doesn't reset). It measures Volt & Watt.

Just received it, connected it to a 2000 watt heater that I knew its consumption and the measurements were accurate. Very good product for its price.

I bought it in 01/2023 and it stopped working on 12/2023, the instant power consumption indicator. Also, it always had low intensity of indications and you had to turn on the light or go at a specific angle to see what it says. Fortunately, I had bought it through Skroutz and the company provided a solution immediately.

Very good for its price, it does exactly what it says. There is difficulty in reading the screen when there is not enough lighting in the room. Its accuracy is similar to a more expensive model that I have when I took measurements from 1-2W up to 100W

It does what it claims. It would be good if it had memory so that if you have placed it in a hard-to-reach spot, you can view the measurements later.

Initially, the measurement of the power of the connected device is done very slowly. The accuracy of the consumption measurement is relatively good. The main problem is the difficulty in reading the dial, which is not illuminated and is very faint, and can only be read up close and in a straight line.

For the money, it's very good. The measurements are accurate, I compared it to another meter of the same brand (ORNO 435) that costs twice as much, and it shows the same wattage. It even shows consumption below 1 Watt. For example, I put in a 0.5 watt LED and it actually displayed half a watt.

It has a deviation of about 5% in its measurements, I checked it with a precision rail meter, but for its price, it is the best choice.

Indeed it counts very accurately, I know what I spend every month, very easy and user-friendly! It is very easy to set up and very good value for its price! I would buy it again!

Economical and effective.
It displays watt, volt, kwh consumption, and cost of consumption in €.
I deduct one star because I would have liked it to have a memory of at least 24 hours of consumption. To start recording kwh from the beginning, you have to restart it to clear its memory.
Regarding the comments about the lack of a backlit screen, I would like to remind you that the device is designed for recording without adding extra power consumption to the owner. It consumes 0.4-0.6 watts when in operation.

Everything is very good so far, the only negative is the screen which is not readable with simple lighting and requires extra lighting with a flashlight. That is why I gave it 4 stars instead of 5.

Very good device, it measures correctly the watts of the devices you have connected (thermal panel 1400 W with 0.16 minutes / kWh, the consumption is half a euro in two hours of continuous operation, it measures the total cost in euros, total kilowatts per hour, shows the voltage of the socket, perfect device

It does its job, but the screen doesn't look good. It should have had a light. However, for its price, it might be the best.

Easy to use and (possibly) expensive. In the devices I know, it shows exactly the same value for consumption. The only negative thing for me is that the kWh indication has a decimal accuracy of 1, which I find insufficient for low-consumption devices.

Good, it does its job.. the only thing that bothers somewhat is its screen, which although it has quite large digits, they are not clearly visible from the side.

It works very well, measures accurately!!
If you know the price per kilowatt-hour, it also calculates the total in euros!
The screen could be illuminated, but it's fine as it is!

Good and user-friendly but... you can't see anything on the screen. You need to be in a place with VERY intense lighting or shine a flashlight on it in order to be able to read the indications. See the image. You can't easily make out what it says.

It is worth its money. It does what it promises and measures accurately. The only downside is the screen that does not light up, making it difficult to read, especially at an angle.

It is good, it does its job.. the only thing that bothers somewhat is its screen, which, although it has quite large digits, they are not clear from the side, in order to see the indications well, you have to look at the screen vertically. Now, as for accuracy, I think it is, if not exactly, very close to the actual consumption. The quality seems good for its price.
