I'll spare you the details, but let's just say that it's about 4 weeks since I received my Ring Doorbell Pro, and despite them sending out 2 replacement pro power kits and now a complete new pack, it's still making an aweful buzzing noise. Despite ordering a new one when I started this whole ordeal, I'm now thinking it's the chime itself. Having checked the list of compatible chimes, I cannot find a single one available in the UK, under £70-odd (which I refuse to pay, after already spending £200 on the doorbell itself). Can anyone tell me where I can get one? 90% of those on the official list appear to US made and not available in the UK.
