So our home is 15 years old, the doorbell stopped working two months ago. I got out a ladder and dismounted the old doorbell to take a look at the problem. It seemed to be an issue of wear, with 15 years of use. Therefore, the repair wasn't an option because the cost to repair would've been more than the doorbell was worth. So I searched online for a cost-effective alternative, this seemed to match the old bell perfectly. It's been installed for little over a month now, seems to be working perfectly. My only qualm is that the old Friedland-Honeywell bell didn't last longer, hopefully this will last at least another 15 years, preferably 20-25 year. The installation was simple, I have no electrical or DIY experience, it's just a matter of matching wires and doing a little research.
