Great deal on these smoke detectors. They're easy to install and I have not had any issues.

I bought two of these to try out alongside some other motion detectors I've already installed.  These units are a great value.  The circuit board inside is way nicer looking than most motion detectors that are anywhere near this price range.  The dual-tech (PIR + microwave) feature is great at eliminating false alarms.  I haven't noticed any false alarms since I put them up over a month ago.  Range is more limited than some detectors that only use PIR, but the tradeoff in reduced/eliminated false alarms is worth it.

When the units arrived I found out that the Pet Immunity feature is actually implemented by the type of lenses that are installed in the unit.  The documentation shows different detection patterns depending on which lenses you have installed.  Unfortunately the other lenses (Wide and Curtain) don't come with the unit, but when I emailed the seller, they were extremely helpful and agreed to sell me (at a very reasonable price) extra sets of lenses.  I wish they would just include all 3 difference types of lenses in the box and increase the price by a few dollars, but currently you need to get them directly from the seller if you want something other than the Pet Immune lenses.  After trying all 3 lenses, the one that's providing the best results for my application is the Wide lens.  The Curtain lens didn't work well for me at all, but for some applications it may be the best one.

Another plus for this detector is the wall mount that comes with it.  Many of the inexpensive detectors out there either don't include a wall mount, or they come with a simple mounting plate.  This unit comes with a nice mount that can swivel left & right, and tilt up & down, and it's also designed to pass the wires through it, so you can mount it right over the hole in your wall and the wire is mostly invisible (you can still see it where it enters the detector at the bottom, but it's not very noticeable).

Overall this appears to be one of the best built units you can get for anywhere close to this price range.  And it's nice that the seller is responsive and helpful... you don't get that with a lot of the less expensive brands.

Very easy to setup, this smoke detectors are a great way to create a mesh network that will communicate with each other in the event of an emergency

It'll be nice to not have to worry about changing the batteries on my new smoke detectors. I used these 2 new sealed units to replace 2 of my older smoke detectors that were over 10 years old.

Purchased Condo and all original smoke detectors were missing.  Purchased First Alert 9120BCP 6 pack and the install was pretty simple.  Removed existing base plates and original connectors but not difficult at all to install either one.  After that snapped new alarms on and tested and they worked great.

These smoke alarms with no battery backup are far superior to the ones with 9 volt batteries. They were easy to plug in to the existing fixture and then mount. I mounted all six in about half an hour because I had to move the step stool to the next location which took time, but it was an easy job all around.

Replaced my plugin smoke detectors from 2003.  Pack of 6 covered my whole house.  Great value, super easy install.  Mounting bracket fits over standard electrical box that the old bracket was connected to.  Less than an hour to replace all 6.

This was a great deal on these. They work well.

Working great. I bought two of these because they are compatible with the smoke detectors that were installed on our remodel 15 years ago. Two of the originals started having false alarms which became very annoying. These have the added carbon monoxide detector for additional safety.

This hard-wired smoke detector has an intelligent design, is very easy to install, can interconnect with other smoke detectors and comes with a 9V backup battery already installed in its front-mounted, easy to access battery compartment.

I bought two and liked those so much I bought six more.

I used all eight to replace the ten-year-old ones my home had because replacement of smoke detectors that are over ten-years-old is recommended by fire safety experts.

At roughly $12 each (depending on quantity purchased) these devices provide very inexpensive protection.

Replacement for 10 year old smoke detectors.  These are the updated models for the old versions.  Same wiring harness as the old model making installation quick and easy.  Great value for the price.  Arrived on time just as scheduled.  Would and have ordered again!

This is an easy to use fire and smoke alarm.  It comes with a 10 year lithium power cell so changing batteries each year is not an issue. It is easy to install and has worked fine so far.

The key for me with all smoke detectors is how long the battery lasts since I assume they will work if there is a fire. So far the battery is working fine. The box says there is a 10 year limited warranty with this product.

The alarm is easy to install. Basically you put a back piece on the smoke detector which activates it and it comes with screws so you can hang it on a wall. I tested the alarm and the sound it makes is loud enough to be heard anywhere in my house. This is thinner than some of the smoke alarms I have so I like that as well.

This is easy to install and works well. I like the idea of a 10 year battery.

This is an easy to install product with clear directions. We had no issues replacing our 25 year old smoke detectors, and were happy to have the added protection of the carbon monoxide detection as well. Please don't let your smoke detectors get as old as ours were. This is a small price to pay to potentially save a life.

Excellent smoke detector for the price. This detector has a dual sensor, which is recommended by firefighters.  My home has wired detectors throughout the house, but one of our rooms doesn't have one, so I purchased this to put in that room. It installed easily, by screwing the base into the ceiling with the included 2 screws and anchors. The battery slot is on the side, so you don't need to remove this from the ceiling or wall to get to the batteries. It is very loud and seems to work quite well.

This was an excellent price for these filters.  We go through 2-3 a year. These filters are any where between $30-$35 where we live.  We have a pellet stove. The air from our pellet stove is channeled through our air ducts so in the winter the filter takes a beating.  I am so happy I found this bargain.
