I replaced my existing smoke detectors with a smoke detector/CO detector combo unit. Installation was easy, fast and perfect. Highly recommended.

Who knows how good the product is until it's used! I replaced 5 smoke only units from this company after 10 years, these seem to be made with same quality.

I had to return one of the detectors I ordered. It was faulty.
The return process was easy and the staff was very helpful. I received my new replacement device in one week, installed it and it operates fine.
