We have two front doors and wanted a wireless doorbell system. The bell unit is located between 15ft and 40 ft from the doors and we have no connection issues at all. Both doors are the same and have a glass panel to which we stuck the push unit and both doors are located under a covered porch, out of direct wind and rain.It is good that you can choose different tones for the different doors, but we went with more traditional rings rather than the numerous (52) and somewhat stupid tones that are available. They are sequentially played and you have to listen to them all to find the ones you like and select!The bell unit conveniently allows other plugs to be used in the adjacent outlet.Not bad for the price and they are working fine after almost a year. So, happy with this purchase.
