I have (for the 3rd day) the zbbridge -p as well as 3 snzb-04 sensors and 2 snzb-03 motion sensors and so far they work perfectly. The sensors that I have connected for now, 1 + 1 door and motion, I activated and tested them at greater distances up to 30 m with intermediate walls, etc., and they sent their signal just fine to the bridge.

Later, as time goes by and as long as I have another review and evaluation for them, I will return.. (* before I did anything with them the first thing I did was update to version 1.6.0)

* ADDITIONALLY
On the 4th day, one of the contact sensors under test was disconnected, which, although it appeared normally in the app, did not respond until I re-added it. I changed the channel to 21 and I am monitoring how it will go from now on regarding disconnections.

* ADDITIONALLY (after completing the 2nd year)
In 2 years of operation, there were 4 - 5 disconnections of the bridge. And as for the temperature sensor, which is located 5 m away with direct line of sight, after its disconnections it requires re-adding, but fortunately it does not lose its previous history.

I read the reviews of the other two and I thought it was right to write mine.
I believe their problem is that they haven't upgraded to version 1.5.0.
I did it immediately before connecting the device. I have connected door sensors, thermometers,
relays, alarm sirens. It works. A total of 17 devices. They all work perfectly.
Day and night for the 15 days I have had it.
I have placed motion sensors on the balcony. Where I have placed it, there are two walls in between and at night we close the shutters and they still work normally. I have created a whole home alarm.
In the ewelink program, by paying a small subscription fee per year (€10), you can create scenarios.
For example, if a motion sensor detects movement and the door opens, then the relay opens with the siren for 30 seconds. And it notifies me as well. Or if you don't want to install a siren, it beeps on its own and notifies you with a simple beep.
Make sure not to place the Bridge at a low height. Not on the floor. Just pay attention to that. Nothing else.
It's worth its money. And compared to other affordable options, it's the best. I believe that the range of ZigBee sensors will grow. Like smoke and gas sensors and others.
This is the PRO version and it can support up to 128 devices. It also has a built-in beeper, which the regular version doesn't have.
It has better range than the regular one, 120 meters in open space. And it's a great price.

26/6/23 It can't handle more than 13-14 devices. It has an issue. While the regular one doesn't.
