We bought our home 2 years ago, it was built in 2005, so 13 years old. Our smoke detector began incessantly beeping at odd hours no matter how many new batteries we put in. Buying the replacement was cheaper here than on Amazon & it arrived within a week. Fit perfectly and no more beeping. We'll be back when others need replacing.

I researched on Amazon and bought on USI store because they had the best price. Also, I read about someone that had to get a replacement but all mine six worked right out of the box. Just installed today. The shipments went to a neighbors blame Fedex on that one. Ordering process was easy and so was installation. I found the comparison charts very useful. I suggest staying with the version you already have installed in your home so you don't have to strip wires.

My home was built in 2004. During the recent time change, I was inspecting the batteries and saw the expiration date stamped into the detectors. After a bit of research and confirming with our fire protection company @ work, I realized I need to replace my 7 smoke detectors which were now almost 12 years old. The USI model in my home, tied into my alarm system and fire sprinklers were easily available on the USI website as a direct replacement the originals. I emailed the company about bulk pricing and although my count of 7 didn't meet bulk pricing they offered me a 15% discount. The shipping was ground and took about a week but all arrived in great condition. I replaced both the detectors and the base as the color on some had yellowed due to exposure to sunlight. Overall am very pleased with the product, website purchasing and customer service. Way to go USI!

I bought 7 of these to replace existing alarms in my home that was built in 2006. The manufacturer recommends changing these out every 10 years but I decided to get ahead of the game a bit after 9 years. The performance on these models has been great and I expect the same 9-10 years of work out of the new ones I just installed. Incidentally, I only needed the inner parts as the outer shell was already wired and connected from the first USI-1204HA alarms that were wired in with the house. The coloring on the outer shell has not faded over the last 9 years and the new inner parts fit beautifully and matched in color too. Very satisfied!
