I previously bought a 10-year battery warranty smoke detector from another company. It was constantly go off and was very difficult to stop. So I returned the smoke detector and bought this smoke detector and so far it's working with no problems

January 5, 2021Best value dual sensor detector
I did a lot of research prior to purchasing 7 of these units for my home. They are the best value dual sensor units on the market and perform really well. I opted for these over the 10yr life battery version as I don't necessrily believe the battery will actually last 10yrs and I will end up having to replace the whole unit. These units come with a Duracell 9V included. I did get one bad unit out of the seven I ordered, the customer service took care of it for me and sent a new one and return label right away.

January 17, 2020Excellent Alarm
Received the MDS300B and immediately tested it. It is a major improvement over the older, false alarm sensors that were installed in our home during construction. Very pleased with this sensor and will soon be ordering a second.
