I have it for about two months. I had from other companies before. The best thing. I never had a disconnection except for one time when the power went out. And it connected again on its own, I didn't do anything. I don't understand how some people have a problem. I am completely satisfied. I solved the WiFi problem on the lower floor in a building with the same clock and three-phase power. Perfect.

When it works, it's good.
The problem is that it disconnects very often.
Many problems.
Don't think about it, you will waste your money.
Desperately with him and I'm going for TP-Link.

I have it for almost two years and I use it in a duplex with three-phase electricity, the first phase being on the ground floor. I am not satisfied at all because it makes many connections and disconnections in the wireless connection that I mainly use, resulting in problems for me at work.

It got on my nerves... after two years of constant crashes and issues, I just threw it away and got a TP link and that's it.

Very good and easy to set up. If you download the app from Android, it is really easy to adjust everything. Something I noticed, I had the PLC and my speakers on the same power strip and it was constantly producing white noise until I changed the outlets and it doesn't have any problem.

One year in my possession, I am satisfied.
I would like instructions in Greek because the setup troubled me.
I am using it on three-phase power with intermediate panels and I have no problem.
Disconnections are very rare.
Overall, I have it with four adapters on three floors and it works great.
It is an excellent choice for three-phase power.

I have had it for 1 year. I have tried it in various outlets and floors and I am satisfied. Obviously, there are some losses and disconnections, but within normal limits. This specific model does not amplify but "transfers" the signal of the router (80-90%) wherever you want, as long as the router is connected to the same panel as the adapter. I mention this because there are single-family houses that have 1 panel per floor. The company says that you can connect other adapters and have coverage in all areas. I will try it and come back with a comment.

I have connected a second adapter and it works perfectly. The connection can be made either as a separate device or via WPS, which essentially clones the settings of the second device with the first, so you have signal everywhere without having to change networks. Also, now that it's summer, I connect the second adapter to the balcony and the signal is excellent!

By far the best powerline option that will solve your hands. In my opinion, Devolo is the top choice. Plug&Play almost, fast communication of the adapters, stable operation, excellent support from Devolo Greece. I have set up a network in a three-phase panel, on 2 floors, and I have internet with ethernet and wireless in a "blind" spot. I recommend it with 1000. It's worth its money

The data transfer from the transmitter (dlan 550 wifi) has a tremendous delay. I bought it to cover the signal gap in the back rooms, but the result didn't justify it. With a full signal, pages require effort to load.
After about 3 months of operation, the transmitter stopped working and I returned it hoping that the new one they would give me would not encounter the same problem.
The situation did not change with the new one, so I would say that the expectations created by devolo to solve my problem with a powerline system were not successful. They all promise more than they can offer, but when you pay extra, you expect greater reliability.

The Devolo powerlines are by far the best. Just like this one. No disconnects, you plug it in and it works. Plug and play, this will pair with the other powerlines you already have, one or more. My older powerlines are in their third year and they work non-stop. As for the price, it is higher than the market equivalents, but it's up to you if you want to get the job done or not. That's why I consider it value for money. My friends who didn't listen to my recommendations are crying over their money.

I was not satisfied with the product... Very unstable connection for its price! I basically have the same connectivity as I do directly from the router!! For some reason, the connection between the two devices is constantly lost without any apparent reason and without me being able to do anything to fix it... And the instruction sheet had incomplete information (it didn't even mention the meaning of the indicators). In general, avoid it!
