Review on SadoTech Waterproof Wireless Doorbell: 1000 Ft Range, LED Flash, Battery Operated - Perfect For Home Use by Brandon Battaglia

This wireless doorbell works great for my apartment. The set up was ridiculously simple and it works exactly as advertised. It comes with both screws and double-sided adhesive to give you the option on how to hang it up. I used the adhesive tape and it's been holding up wonderfully. I like the see-through/removable cap at the bottom of the doorbell where it allows you to write something (I wrote my apartment unit). Both units light up a blue color when the bell is rung. There's so many ringtone options, including multiple holiday tunes (Jingle Bell, etc). I would definitely recommend this doorbell and I'm glad I bought this one.
