"I had a 12 year old model 4120SB that started malfunctioning. I called the hot line number on the back of the unit and was advised that the unit was beyond it's expected reliability date and it was recommended that i replace all 4 units in my home. I have ordered the 9120B unit that the site recommends as the proper replacement unit. Reviews said that it was easy to install and operated well. I expect that to be the case."
"Went to Home Depot they do not carry your brand shopped on line which I never do"
"Thanks for picking up the phone to reassure me that the old 9120 hardware works with the 91230 B"
"Found the replacement that I was looking for."
"Had to do the above info three times before it "took!" :-("
"great experience!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"
"The biggest concern I have is in the images. I saw several images of the same detector I am looking for that all seem to be the same thing, but with vastly different prices. I also noticed that buying direct from you here has nearly halved the price from the same detector at hardware stores."
"Found what I needed and it was easy to order."
"Most cost effective pricing we could find!"
"good price, easy check out."
"I had the onelink system before to supplement our outdated wire in system which only has detectors on each level. I got this to add in the bedrooms. I love that it would state locations. I also like the peace of mind it broought. that's 10 years ago now, time for more."
"Found what I needed and got a good price."
"Disappointed in last product not lasting seven years but have to replace it as this is what building inspector requires we use."
"thanks for free shipping "
"Took awhile to figure out what we really wanted/needed... in the end, it all added up to a lot of $$ to replace almost all the now expired detectors in our only 6 year old house... then disappointed to find that we don't even get free shipping for all of it! Well, thankfully the detectors are now good for 10 years. Just hope we don't have any fires or CO problems during the week they are being shipped, as we've had to disconnect several chirping detectors over the past week...
