I've been using it for a long time, it's stable. There was one moment that the router actually stopped distributing 4G Internet. First I checked the SIM card in the phone, everything worked, I sinned precisely on the router. But then it turned out that on my tariff it is forbidden to use a SIM card in routers. It is very interesting that before everything worked and I did not notice it. As a result, I changed the SIM card to one that can work with routers, and now everything is fine again.
