Because of the 5G that cannot be turned off, my head hurts when I turn it on. Now I have it and it just sits there hoping they release an update with more settings.

Much better WIFI than with the OTE router, without connection switches from floor to floor. Very easy installation. The downside is that apart from the first one that connects with a cable, the second struggles to maintain a strong signal.

4 + 1 HALO H80X
***** Speed at the last one that it has and the router.
***** Installation
***** Low operating temperature
***** Great help with the 3 ethernet ports
* Signal strength connection at the last halo, it does not connect to the closest one but to the central one and there is no manual selection, no matter how much effort was made with the position in the software (1st-2nd-3rd+) no change.
* Halo that while it is connected and has the white indicator, the software sees it as offline.

Easy installation, beautiful and discreet devices. Very good speeds, reaching the speed of the connection. But: You cannot choose the wifi broadcasting channel, which it does automatically, resulting in my old laptop not seeing the network, as the Halo chose channel 12 and I cannot adjust it. Now I have to get an external wifi antenna. If the Halos are at relatively close distances, the connected device (phone, tablet, etc.) does not connect to the nearest one as you move but remains connected to the Halo it was previously connected to.

Low operating temperature
very easy installation
speed the same as the router.
very good connection between central and peripheral.
sleek.
Excellent price.
Quite good app

Regarding Double kit
With two walls and a distance of 8 meters, it provides a speed of 470 mps
(on 500 line) as well as wired. Highly recommended

First impressions: extremely quick and easy installation through the app, satisfactory coverage despite obstacles, and flawless data transfer at full speed, as the 2nd node provided the reference speed of the modem (100Mbps Down / 10 Mbps Up) to a computer connected via ethernet without any issues. On the downside, there was a slight insecurity during the initial setup because the color of the indicator during the device's startup does not distinguish between green and yellow; however, the goal is to turn blue ― therefore, after a short period (1-2 minutes at most), everything is resolved and the anxiety passes irreversibly. Overall: an extremely aesthetically pleasing device that exudes an air of reliability and sturdiness despite coming from Mercusys, which is the budget line of TP Link. If it continues to operate reliably, it is highly recommended!

Very easy setup. I really had all 3 set up within five minutes out of the box and they worked perfectly. Very good coverage and finally, I stopped having issues with the signal at home. It even works in the car if I have parked nearby.

I already had the 3 H50g and added 2 H80x for better coverage of the area. They work perfectly. The app is quite user-friendly

I gave it as a gift to my brother, he didn't complain (he's very picky) so it's amazing!!!!!!

Very easy installation, daily phone support in Greek for any problem and very user-friendly app.

I bought the set of 2. I have a long narrow house and I got them to get signal in the bedroom but also to reach the downstairs floor. I can say that they have excellent range and speed on both floors without any loss. Really a very good choice, they are worth their money.

Very easy to set up, works perfectly. Sends internet to two floors above (one device on each floor) with minimal loss!

Replaced two separate routers that were broadcasting their own WiFi SSID. In addition to the excellent coverage, it dramatically improved the quality of the connection by removing another device that was trying to transmit on one of the WiFi frequencies. Using the Guest Network for IoT devices (cameras, bulbs, etc.) keeps your main network free from poorly written management software and potential back doors. The 2.4GHz can be a bit quirky with older devices, so be prepared to update their firmware if allowed or, worst case, use a 2.4GHz only repeater (the same company offers them at a very affordable price) to support them. Highly recommended!

It does what it says. I connected it with an ethernet cable to the router and it covered the whole house.
Flawless in terms of speed.
The application is simple with plenty of settings. Perhaps someone more experienced would like more flexibility in customization.

Really excellent considering the price. The installation was more than easy (via an extremely well-designed application), the performance is outstanding to such an extent that it is difficult to find any area of the house with a problem anymore. Roaming is seamless while the additional options provided by the application (e.g. qos, parental control, etc.) are always welcome. It does what it promises and more. It remains to be further tested under high load.

Very good access point with a large signal range. Ideal for someone who needs to cover large spaces.
