I have used the X Series Products since February now (I was Part of the Early Access programm) and i had no issues whatsoever. Setting it up took me maybe a minute as it pretty much does it all itself. Same with the Bridge.
I also really like that it uses USB C to charge its internal battery. No more having to buy batteries all the time.
I am overall extremely happy with it as I had no issues with it at all (unlike the company i had a smart thermostat from before switching to tado)
I can overall only recommend it. And I hope you guys can enjoy it aswell!
