Review on Wireless Doorbells For Home, Businesses & Classrooms - SadoTech Easy-To-Use Battery Operated W/LED Flash (1 Ringer + 2 Receivers) by Jay Williamson

For the last year or so my Grandma has casually complained that she often misses visiting neighbors or package deliveries because she can not hear her doorbell from her back sunporch, where she likes to sit. We suggested moving the receiver, but she didn't want to do that because then she wouldn't be able to hear it in other rooms of the house, such as her bedroom, bathroom, kitchen, and/or livingroom. Well when the batteries started to give, and she brought up the problem another time, I figured there had to be a better solution then just replacing them and continuing on with a doorbell she could only hear in certain areas of the house, assuming she was watching TV (which she so often does). So I got online, this product popped up as an amazon favorite with great reviews, and I ordered it.She loves it. She can now hear it ring throughout the house, and the wireless connection is strong enough that even with the lightest push of the button both receivers chime, and in sync with each other. I had worried that with one receiver being an additional 30-40 feet from the remote bell then the other receiver, that they would chime out of sync, and create an awful havoc of a sound if you were in, say, the kitchen, where you can hear both the one from the sun porch and one nearest the front door. So it was nice knowing that was not going to be an issue.Another plus, that she liked, is that these receivers are much smaller, and on plugs. Her previous wireless receiver was very bulky, and on battery power, and she gets a lot of door traffic. At least once a year the two, giant, D-sized, batteries needed to be replaced in order for the receiver to pick up the more distant connection. This is no longer a problem, and she now has both receivers plugged into outlets that are out of sight, as she no longer needs to get behind the furniture every time she needs to change the batteries. She also seems to like the remote button more as well, it's modern, simple, and eye catching; she even remarked this week that her food delivery service, that she has never heard ring the bell before when dropping off her frozen packages, rang it this time.Overall this was a very inexpensive gift that solved a daily inconvenience in an old ladies life, she couldn't of been happier that someone finally took five seconds to solve it for her; I only feel bad it took me so long to think about it.
