Review title: Just what I needed, but not so quiet anymore
Product review: This transformer is 16volt 15 watt and just what I needed (exact match for the broken one), no local hardware stores carry it just the lower powered ones. It took 5 minutes to install this replacement and now my doorbell is ringing again and possibly a little louder then before. UPDATE it is now 8 months since installation and the transformer is humming rather loudly (luckily it is located in the garage so the noise is not too bothersome) the doorbell is still functioning at this time but I do not know for how long. I will update when it stops functioning altogether. I am disappointed(reduced rating to 4 stars) in the apparent short working life of this transformer as the previous one lasted for years.
