Review on SadoTech'S Wireless Doorbell Kit: 1000-Ft Range, Waterproof And Loaded With 52 Chimes And LED Lights by Kenneth Mills

I had a couple of cheap ones ($17 ea from wallyworld) that kept failing after about a year. Bought these last week. All easy and good so far, time will tell about durability, but set up was eash. Only problem was (and Best Buy should look into this) a card in there says, Register the product, get a free gift. I did, but on the page to select gift they are all OUT OF STOCK except a spare button.which worked for me. I selected it, and then the next page said OUT OF STOCK SELECT ANOTHER ITEM. Really? They should rob some packages to fill orders, or take down the offer. That left a bad taste in my mouth.
