Loud & Clear!,
Verified Purchase(What is this?)
This review is from: Byron Sentry BY212 100m Wireless Portable and Plug-In Door Chime Kit with 6 Sounds (DIY & Tools)
I bought these for my aunt who needed louder door bells and these allowed her to have one in the hall and a second anywhere where there was a mains plug, they were easy to set ip & work well.
