Quality of Awox/Eglo lights

Hi, I have some ceiling lights from Awox/Eglo.

In fact, I have two identical lamps, one of which reports as Awox and one as Eglo, which I find strange.

Both lose the connection to the Zigbee network from time to time. I then have to either disconnect the power supply to the lamps or restart Z2M so that I can control the lamps again.

What are your experiences with the brand? Can the problem be solved? I have a Sonoff USB dongle (I think the E variant. Should I switch to P?)
