Great !

 This thing is totally worth it if you don't already have a doorbell and want an easy fast to install a doorbell. Small and unobtrusive. It comes with two transmitters, three receivers, two screw wall mounts, two double-sided stickers.  For the price, I can't complain. This product claims waterproof, but we shall see because the transmitters don't look very well built to withstand rain and water splash. Just a plastic cover with two clips, no weather seal strips, and the chip is sitting right inside.  #RankBoosterReview #Sponsored #e elepowstar
