Worked great
All alarms in house I bought were 14 years old. Same brand different model. Plugs were identical, but had to change the bases. These worked great. I like not having to change batteries every year. Cheaper in the long run.

Fast Shipping and Reasonable Price
I have not installed the alarms yet, but they came quickly and the price was right. I purchased this product for its dual sensors and hardwired interconnect capabilities.

Great replacement for old sensors
Our old smoke detectors were about 10 years old and starting to give false alarms. I ordered 7 of these and received them promptly. I thought I could use the same plugs from the old Kidde detectors, but found that they were wired differently than these new ones. Installation was quick and easy and I love the 10 year battery life. No chirping in the future!

Hard wired smoke detector
I selected this product because it has the 10 year lithium battery that does not need changing. This is a great feature.

MI106S unit
Chose this unit primarily because my old alarms were USI. They lasted much longer than their expected lifespan. Also because of the 10 yr battery backup. Installation was simple and quick. I won't miss replacing the batteries like I used to do.

Highly recommend Universal Security Store.
It was a pleasure doing business with this company, especially the nice lady in the office who helped with a billing question—very polite and helpful. Shipping was fast and product arrived in good shape. At 70 years old, I was on my own with replacing 7 wired alarms. USI instructions are thorough and easy to understand. I also did other reading about dealing with electrical wiring. After turning off the power supply, which was wired separately from the rest of the house, I also used a voltage meter to be sure no power was detectable. Although, it would have been nice to just plug in the existing harness, I used the existing wiring nuts with the connector that came in the box with the USI alarms. I used the third yellow wire for interconnecting the alarms. I pulled the tag to activate the 10-year battery and each alarm sounded as expected to ensure activation. After I put the seventh alarm in the backplate, I turned on the power and all lights were green. I tested each alarm and all worked and I could hear that they were properly interconnected. One try and done! It is important to know that if the backplate screws are too tight, the alarm will not fit under the tabs for hanging it.
