Review title: Good product - minor backward compatibility issue with mount
Product review: I bought this product to replace a defective older BRK Smoke/CO alarm unit (can't remember the model #, maybe SC6120?) about a month ago. This model is the official replacement for my older unit. I was hoping to just be able to plug this into the existing BRK mount but it didn't fit. I had to remove the old mount and install the new mount plate that came with the product. Not a big deal but a little extra work. So far I haven't encountered any problems with the new unit.
