Review: Works Great, Now I Just Need Less Annoying Visitors - For the price, this doorbell is a steal. Easy to install, loud enough to hear even if I’m pretending not to be home, and has a bunch of chime options—including some that make my house feel way fancier than it actually is. Only downside? Now people actually use it. If only it came with a feature that scared off solicitors and in-laws, it would be perfect. Five stars for functionality, but I might start pretending it’s broken.
