2k Doorbell & Byron 776

Hi all, I’ve been looking at switching my doorbell from battery power to wired in and have been looking into the Byron 776 chime and transformer. There are loads of videos online using this chime with the Ring doorbell, but nothing for the Eufy one. The reviews on Amazon seem to say it works, but the 8v output seems low when comparing to what Eufy recommend.

Has anyone successfully used this one? Or can another be recommended in the UK? Ideally I’d like a chime and transformer together if possible.

Thanks
