Review on Coolqiya Wireless Doorbells Chimes For Home With 2 Remote Door Bell Buttons Waterproof And 1 Plug In Receiver, No Battery Required For Receiver 58 Ringtones by Michael Hawkins

I was most pleased with this product and its ease of installation, clearness of instructions, and performance.Nice choice of music selection and easy pairing of the receivers to the push buttons. Be advised it does come with batteries in the push buttons. The receivers plug into a normal plug outlet. I did not adjust the volume as it seemed quite loud enough as sent. There are flashing blue lights in the center that also blink when the receiver is activated.I suggest getting multiple receivers as you can place them around the rooms in the house for better coverage. I put one in the kitchen, one in the bedroom and one in the living room. I may move one to the downstairs basement.Over all I am most satisfied with this device. Only time will tell how well it lasts.
