Wireless Doorbell, Aogek Waterproof Chime Kit with 52 Melodies & Adjustable Volume; 1 Receiver&1 Push Button,300M/1000Feet Operating Range Portable Plug-in（Soho Style）

I couldn't hear my door bell from one side of my home and needed something to be able to hear when someone was at the door. This door bell came with both a adhesive backing option or a screw in option. I used the adhesive backing by first cleaning the area next to my existing door bell with rubbing alcohol to get the best stick. This option is great for those who already have a door bell or are renting and can't use the screws. I love that I simply had to plug in the other part of where the bell rings and choose from different volumes and sounds. I can adjust the tune and volume which many others don't offer.

Easy installation and control of volume and ring tones. It actually works!! I live on the 3rd floor and its within range.

Works great and easy to apply to wall

Great product.

Omg this is the best doorbell EVER! The installation was so easy all I had to do was plug in the chime unit into an outlet. That's it! It doesn't require any batteries. There are over 50 melodies to choose from and they are all awesome. The transmitter can be installed with a double sided tape or screws which are both included. The great thing about it is that you can choose how loud you want to keep it. I received this product for free in exchange for my honest opinion.
