Question: what songs are included?
Document: This door chime is great! Has lots of pre-recorded songs and is very easy to add your own songs with IPod!
The songs are great fun, and I love the option to record other things. The product came quickly, and it works well.
Easy to install....has a LOT of songs to choose from, some instrumental, some vocal....Bought it because we live in Houston and it has a mariachi band playing La Cucaracha--very funny!! !Can adjust volume, great selections for Holidays...
I hate loud obnoxious doorbells and when we moved to our new home in the &#34;country&#34; our home did not even have a doorbell. After months of quiet and missed visits because we never heard our friends or the UPS guy knocking we decided we needed a doorbell. We chose the iChime because it had such a variety of ring tones/songs. We love it!
I like to experiment with different sounds based on who I know will be coming over. Everyone who hears it wants one! Right now I have it setup to play my six year son saying "I'll be right there!" Should be fun at Christmas time to have it play the built in Holiday songs like Jingle Bells and Deck the Halls.
Installed it last year and still working great. Easy to install. I did not need to change any of wires in my house, they just perfectly match.I thought the batteries will not last long but so far no problem for over a year, still sound loud. Like the difference positions with difference great songs. My son like to record his voice to scare or welcome the visitors. Cool!
Con: The doorbell is off-white not white, certainly not the most attractive doorbell if its in a visible spot (Sad face) - ours is not so it didn't matter too much, even though I wanted a more attractive piece for the price.Pros: That being said, I love all the fun sounds and I love that we can record different songs - we recorded "GO GATORS" fight song for football parties and currently we are using "Gangham Style" because it is hilarious.
Definitely noticable whatever I'm doing. Replacement installation and set up for the base unit was simple, the remote unit required me to run bell wire to back of house. At the cost of this unit they should definitely impove the speaker clarity and volume. The design and programming included are unique and impressive.
we really *love* our new doorbell ... it's easy to use, though i have not tried to load my own sound clips yet. there are plenty of preset musical effects that can be changed with the turn of the knob. we have a very open floor plan and we keep the volume on the loudest setting. it's sufficient. our kids especially like it, but i find the adults who visit pressing the doorbell over and over to hear all the different sounds!
the different chimes are fun - barking dos; &#34;open up; police!&#34; and more. But boo; the whole thing stopped working within one year!
