## Customer Reviews

### ⭐⭐⭐⭐ Attractive, compact design; adequate wireless range; sufficient volume to be heard throughout the house.
*by J***F on May 10, 2016*

Both the doorbell unit and the remote button are solidly constructed, a welcome change from my previous wireless doorbell.As I only just received it yesterday, I don't have any idea yet of the battery life - but for those who object to the idea of having to change batteries, it can also be powered via USB (even a cheap, low-amperage wall charger seems to suffice). Copying MP3 files to the unit is simple (even though the product brochure on Swann Security's website indicates "Windows based PC only", it worked fine with Linux). Volume settings and song selection are easily performed from the silver ring on the main unit. In my house, the doorbell can be heard down in the basement even when the volume isn't all the way up.One nice surprise was that the manual wasn't badly translated into English; it was written by someone with genuine fluency in English, as well as a sense of humor. (A second manual, in French, was also included, but I can't judge its quality.)Wireless frequency is easily changed via the DIP switches in the main unit and button remote; however, the switch positions are reversed (the switches are "on" in the down position on the main unit, and in the up position on the remote, a fact the manual neglected to mention).The unit's two minor failings are the second-and-a-half lag time between when the button is pressed and when the MP3 begins playing, and the fact that pressing the button while the MP3 is playing restarts it from the beginning. The 1.5-second latency doesn't sound like much, but when one is used to immediate doorbell response, the natural inclination is to press it again when no sound is heard (which sometimes seems to restart the delay, and other times does not).

### ⭐⭐⭐⭐⭐ Love this!
*by S***L on June 2, 2017*

This doorbell is awesome! I love programming it for different holidays and seasons. It is easy and the batteries work well. I wish there was a way to attach the doorbell without the sticky back. I use it for my classroom and it needs to be removed every summer. Not sure how to reattach it. It was also reasonably priced.Year update- It got knocked off the wall, and now it is dead. It was amazing up until it fell off the wall. I wish it came with a sturdy way to attach it to the wall. It just has a way to hang it, and it's not very practical.

### ⭐ This doorbell is a piece of garbage. it "worked" for a couple of months
*by C***D on January 3, 2017*

This doorbell is a piece of garbage. it "worked" for a couple of months. I say worked because in trying to shorten an mp3 file, the software did not work. I had to put the whole 1 minute 54 second file on it. Around Thanksgiving, it stopped working altogether. It's my fault that I didn't due anything about it until now, but with the holidays and the fact that we don't have that many visitors that use the door chime, I put it off until the New Year. The batteries are fine, but it just won'T play the tune.Highly overprice and not reliable.
