My original doorbell was hard to hear upstairs, so I got this. It works great. Needed to open the transmitter to remove the plastic cover off battery before it worked fully. Didn't see that in notes. Back cover was a little hard to remove. It gave directions to sync the receiver with the transmitter, but I think they were already done. Easy to set up and use, great product for the price. Would definitely recommend.
