A very easy to install and use product... for as long as it works!!!
Unfortunately, it freezes very often (every few hours or even more frequently), causing it to stop working (its wifi shuts down and it becomes completely disabled, its LEDs turn off and it is not accessible through its IP), so it is useless in practice.
I tried firmware upgrade, but it didn't make any difference. Unfortunately, it will probably end up in device recycling. :(

Excellent choice
It synchronized immediately with the router, runs smoothly even in difficult areas, e.g... outside a stone house with almost a meter thick wall, like the one I live in.
Even after a power outage, I didn't need to do anything.
It's worth buying it!!

Easy installation through mobile application, accepts firmware updates (until recently I don't know about the future) although you have to install them, you can direct the signal by changing the positions of the antennas either upwards or downwards, it is small and elegant so it goes unnoticed inside the house. Overall, it's worth its money.

In a few days, it will be a week since I have had this specific product and I feel completely satisfied. Easy installation. You simply plug it into the socket and connect it to the internet via an ethernet cable, just like you would with a router. You follow the instructions and the rest happens automatically... The signal is more than satisfactory, as we have several people connected and yet it feels like having the router right next to you, even though there is a distance of two floors. For now, it seems to be worth its money and more.

Perfect! The installation with the application you download on your mobile phone takes at most two minutes and the signal is full even on lower floors with walls and stairs in between!

For the first month that I have been using it, I am satisfied....
Edit. 9_11_2018 very good! I bought a second one for my father's!

Perfect in use and very easy, very good signal, perfect.
I live on the ground floor and on the other side of the building and despite the distance of up to 10 meters from the router and in between. Obstacles of 2-3 walls and 1 ceiling with plasterboard and with a possible obstacle of the building's stairs.
Perfect tool that relieved me from trouble

Set up with a ZTE router from Cosmote.
10 meters distance, with 2 walls in between.
Very good range, no disconnections.
Easy installation in one minute.

At the price it is currently being sold (21€ for 29/12/2017), it is value for money.

Good little machine, well done. Installed it on the socket at a height of 2 meters, with a distance of 12 meters from the router and interference from 4 walls, full signal.

Amazing machine...200m pairing with visual contact, without losing signal...no disconnections, excellent range and speeds as if I'm next to the router.

However, it does not have detailed signal measurement when detecting networks and the signal indicators (weak, good, etc.) do not always correspond to reality...I don't know what differences it has with version 1 of the same machine apart from its appearance (more distinctive LEDs and different buttons).

Also, in its function as an access point, it only works as a network distribution device and not as a client, meaning it does not function as a wireless card connected to the computer that will be connected to the router.

For those who have complaints about connection stability, simply try changing channels until you find the one with the least interference...a strong signal alone is not enough...it's better to have a weaker and less noisy one.
