Review on AVANTEK Wireless Doorbell: 1300Ft Range, 52 Melodies, 5 Volumes & LED Flash - Waterproof Chime Kit by Bryan Gallardo

I deliberately waited to post a review until after I'd had this for a while so that I could really test it out. This doorbell is AWESOME.I have metal siding on my house, and I've had NO problems with it working properly. I have the button on the front door and the chime plugged in my kitchen (which is pretty much in the center of my house), and it works just fine.Also, if you live somewhere with brutally cold winters (as I do!), you should have no problems with battery life or reception. I'd purchased a cheaper doorbell before that worked OK in the summer (but the range was limited; I had to plug the receiver in the living room), but the batteries would die within a day or two in the winter. This one has worked perfectly, even in the coldest weather.It has three volume settings and a silent mode, and believe you me, it's pretty LOUD at the highest volume; I can hear this doorbell in every room of my house, and part of my basement. Plus, it has a flashing light on it so you can turn the volume off and still know if someone rings the bell; the light is small, mind you, but it still catches the eye.Finally, it has a bunch of different sounds (coocoo clock, door slamming, cats meowing, dogs barking), songs (Ode to Joy - my personal favorite, Fur Elise, Christmas tunes, patriotic tunes), and just general ring tones that you can cycle through and change with the seasons, or whenever you get tired of hearing the same chime over and over. I would definitely buy it again.
