Question: How is the sound quality of the rings?
Document: I purchased this doorbell after I saw it at a friend's home. It is a &#34;classy&#34; doorbell set with a large bell push and high quality sound tones. It is not your every day doorbell!I had some difficulty releasing the back of the bell push.
After less than two years stopped working. Changed batteries in both units, hit reset buttons in both units, checked to make sure code setting was the same between the units (both at factory default). LED indicates signal being received but zero sound at any of the selections. Great build quality and great sound - when it actually worked. Save your $150 and buy a cheap, Asian-built unit that just needs batteries every few years....but actually works. Pure Euro Trash.
Product is great and is just as described and I would recommend it to anyone in search of a quality product.
It is as advertised. I am more than pleased with the quality of this doorbell. I only wish it could have had a hard-wire option for the doorbell ringer itself. I just set it up and will have to wait and see how it holds up.
This looks great and was easy to install, the chimes,all have a,rich, powerful sound, and it looks wonderful in any room.
Doorbell has lived up to expectations in terms of range, sound and appearance. Easy to install. Worth the cost in comparison to other wireless doorbells on the market.
I have had this somewhat expensive wireless doorbell for several months now, and it has worked perfectly for me. The rings are very loud and can be heard throughout my entire house (and I am a little hard of hearing). I liked the choice of rings, but some are rather bizarre. I will say, however, that the manufacturers claims of great engineering are somewhat overblown. The push button is not easy to open up without damaging it, and the mounting system does not appear to be particularly sturdy.
Signal between transmitter (doorbell) and receiver is not strong enough to go through concrete block walls, so doorbell must be within 50 feet of sound generator. I couldn't place the sound generator anyplace that was useful or desirable. Also, choices of sounds was limited to 5 rather boring sounds.
Although this item did last for two years it was never trouble free. And when it did quit working we could really see no reason for it. My husband is an electrical engineer and couldn't see why the machine no longer got electricity. We really don't want to have to buy a doorbell more than once in ten years or so. Too bad. It looked nice and I liked the sound.
I am hard of hearing, and a lover of style.This doorbell is perfect. I've had it 6 months. As others have said, the interior chime looks great, the sound is loud and clear. Worth every penny.I bought this because I wasted 3 grand on a Bang and Olufsen 6 phone system that is just a piece of junk. Line 2 of that is hard wired to a doorbell.
