Verified Purchase(What's this?)
This review is from: SadoTech Model C Wireless Doorbell Operating at over 500-feet Range with Over 50 Chimes, No Batteries Required for Receiver, (White), Fixed Code C Series (Tools & Home Improvement)
It's compact and sleek and seems to work well (though I haven't pushed its range); what more does one need? There are quite a few songs/tones, most of which are rather cheesy-sounding. I set mine to the classic "ding-dong" doorbell. But if you want Mozart to play on an electric piano, that can be arranged. . . .
