Review on Wireless Doorbell For Home - Long Range Battery Operated, 1000 Feet, LED Flash, 1 Button + 2 Receivers, Matte Black Finish By SadoTech by John Roby

Received SadoTech Model CXR wireless doorbell today. Let me say up front, that this particular model comes with two PLUG-IN receivers that must be plugged into a regular 110 wall socket. The transmitter that you attach to the wall outside your home is battery operated. Instructions were easy to follow. I like that each receiver can be programmed with 1 of 52 available tones. It's actually a combination of tones or musical jingles you can choose from. Also, when the button on transmitter is pressed, the blue ring on all 3 pieces lights up momentarily. Programming each receiver takes less than 15 seconds. The outside transmitter can be mounted with 2-sided tape or anchors, both of which are included. Battery for transmitter is also included. Instructions advise you to mount receivers to wall sockets located at least 3 ft high for better reception. My chosen locations were both at wall sockets located at 1 ft levels. That wasn't a problem at all, so don't be alarmed if you think these won't work if plugged into a socket at floor level. Signal from transmitter is plenty strong. I also like that this gives you the flexibility of moving your receivers or changing tone/volume if desired. I'm very happy with this product for the price.This is nitpicking, but my only complaint is Product Registration. SadoTech encourages registration and offers a choice of free item, e-booklet with tips & tricks, discount offers and faster support response times as an incentive to register. I went to the linked website and entered my information, but when it came time to complete registration, the last step took me into a blank white page where it remained with every repeated attempt. I attempted registration via my 4G Iphone using cell and wifi from home. I then went down the street to a public wifi and still no luck. Tried via 4G again and finally one last attempt from home through my PC. Oh well, no registration, but I'm happy with the product.
