SadotechWireless Doorbell - Model CXR, 1 Push Button, Cordless, Waterproof Transmitter w/ 2 Receivers - Battery Operated Door Bells w/ 52 Chimes & 4 Volume Settings – Gray

This is a winner: easiest of installs, great range, great functional volume control, great price-performer, and a different ringtone with each unit for (almost) every week of the year . We went years with a non-working doorbell, then we discovered this choice. We installed one unit downstairs, one upstairs & have complete coverage in our 2400 sq. foot home.A couple of minor issues: - lose the ringtone selection with a power outage & each unit must be reset - not the most attractive aesthetically, but we hid the units in out-of-the-way places - it remains to be seen how long the double-sided tape & battery will last on the outside remote button given our annual temperature variations of 0F to 100F....more curious than concerned

Easy to install, great sound quality and small size that looks good on our glass office door.

These work very well so far. Have one in basement and the other on main floor. Only issue is it is a bit complicated if you want to change to a different ring type.

I was pleased with both the look and functionality of the doorbell. I purchased one bell and 2 receivers.

Quick install. I put it up yesterday in about 5 mins. We live in a pretty damp environment in the Pacific Northwest, so I hope it withstands the moisture. I would have preferred it if it was weatherproof as opposed to weather resistant. I added some electrical tape around the transmitter where the two haves come together. That is just an attempt to keep the innards dry... Time will tell.
