“Standard wireless doorbells running on batteries have poor-quality and hence very unreliable transmitters to which I could find no alternative until this kinetic model. If it lives up to its promise, that could solve a longstanding and doubtless widespread problem.
The equipment looks good, though it didn’t include the promised mounting plate, so I used double-faced industrial tape. The instructions should specify that all transmitters to a single receiver will elicit the same ringtone; if you want different ringtones from different transmitters, you’ll need multiple receivers.”
