I've had it for about 2 weeks and I can say that it is very fair for its price. It usually gets 600 download, 100 upload with a latency of 40ms. Stable WiFi and stable operation, but it needs some work in terms of firmware. I can't lock the band and that's why I have a large discrepancy from the measurements of my phone (~1000 down, 120 up). I will get back to you when I have updates.

Perfect router.
I used it with Cosmote unlimited. It connected immediately and without any issues. The installation is a breeze and for the past 2 months, there have been no disconnections.
In a village where my iPhone got 120 Mbps indoors, this one gets 150.
I also connected 2 more Deco X10 to it, and now the whole house has excellent WiFi signal.

p.s. The SIM should be inserted into a phone first to disable the PIN and activate 5G (send SMS to Cosmote)

Perfect where there is coverage. I have achieved download speeds from 150 to 1000 with Cosmote. 4 stars because there are better antennas available, but they are also more expensive

While it shows normal 5g or 4g connection, the signal suddenly freezes and this happens constantly until you restart it and then the same thing happens again. I returned it to see what's going on. Not recommended.

The wifi signal is worse than that of the free router from Cosmote.

After contacting the company and testing every possible scenario, it seems that someone should be able to connect reliably and beyond five meters. We concluded that the device should be returned or taken for service.
