Even though there are many, many types of smoke detectors available, there really isn't much choice. Literature on fire safety says to get one that has both the ionization feature and the photoelectric feature. You see many that only have one feature or they combine it with a carbon monoxide detector. Get a smoke detector that focuses on its job. Get a separate carbon monoxide detector and locate it down at your level instead of high on a ceiling.
The alarm is nice and loud, which I need. I wish it could wirelessly activate the other alarms when it goes off. You have to remove the smoke detector to change the battery, but that is very easy to do.
Don't forget to mark on your long term calendar to replace it in 8-10 years. The ionization feature may not work after that.

I purchased 4 Kidde PI9000 Dual mode detectors to replace working, but old detectors in our home. One failed within a month and after returning to Kidde at my expense they replaced it. Took at least 4 weeks to get the replacement. A few months later another failed, again I sent it back and received a replacement. Now at less than 2 years, two more have failed. I bought 4, I've had 4 failures, and I have two working at the moment.
The failure mode for the units was a constant chirping, the same sound they make when the battery is low, except on the failed units changing batterers, even different types would not stop the beeping.
I can't see how this failure rate is acceptable by any standard.

Two of Three units have not worked since purchase. Have tried calling Kidde multiple times. Once got hung up on by rep (after waiting 11 minutes on hold to be connected to a rep) because I asked where to find information she was asking for on product. I called again and (after waiting 14 minutes on hold to be connected to a rep)got immediate hang up by customer service without being able to talk to a rep.

I bought 3 of this in September 2008, and as of now, July 2010, 2 out of them have already died within two years. They died in the same way: just beep for nothing and would not stop. If you push "HUSH" button, then they silence for 10 minutes and resume beeping for nothing. This is crap, expensive crap!

I purchased several of these alarms for use in our home's bedrooms. Today, I came home to the sound of a smoke alarm going off. In our bedroom.
I rushed upstairs, but all seemed to be well. The alarm was continuous, just like an actual smoke alarm, rather than a low battery signal, which has a longer pause between beeps. I changed the battery, and the result was the same. It didn't matter that there wasn't -- thankfully -- so much as a spark or whiff of smoke in sight (or smell.) I took an identical alarm out of another room and placed it in our room. No alarm. And, yes, the self-test worked.
Looks like I'll have to buy another. I am only glad that the alarm didn't go off at, say, three am. I can only wonder if the unit would have worked in the event of an actual fire, as I have no way of diagnosing the cause of its malfunction. Needless to say, I'm strongly considering finding a comparable unit from another manufacturer.

I own 8 of these units, all of which were installed in Spring 2007 new from the box. I like that they are cost-effective, and are low-profile on my ceilings. They blend in very well.
I also like the fact that the manufacturer claims this sensor can sense fast-flaming fires, as well as slow smoldering fires with its "dual" detection features. That is very appealing. And, the alarm is VERY loud. That is all good news!
Other reviewers have mentioned these units dying or going off the deep end after a short amount of time. Well, I can add that 1 of my 8 units has finally died after just over 3 years in use. We came home from dinner one evening to one of these alarms going off (not the dead battery chirp, but a full siren). After checking for smoke, fire, etc., and determining there was neither, I pulled the active alarm off the ceiling. I switched it to another location far away from its previous location, and reset it, only to have the alarm sound over and over again. Thus, it seems clear that it is defective.
That opens up the following question -- having never had a fire, how much can we consumers rely on this model if they randomly go defective after short periods of time? While I regularly test my units, and change batteries regularly, having one die and/or malfunction for no reason raises a concern with me as to whether or not these alarms will work as claimed in the event of a real fire.
Statistically apeaking, they probably will work fine in a real fire. However, when one's life depends on it, it is certainly concerning that they can simply stop working as designed after only a short period of time. What if one stops working and does not make a sound, then a fire starts??? I know that is very unlikely, but it's worth considering.
So, to the extent that 7 of my 8 units still seem to be fine, I guess this is an OK product. The alarm is VERY loud and would do a good job if it works as designed in a fire (I've never had a fire, so I don't know what will happen in a real fire situation). I can only guess, since they have not been tested in a real situation.

I have created a 9 volt power supply for my main residence and a vacation home, used to power dual sensor smoke alarms, that are tied into my security systems. First Alert sensors at the vacation home repeatedly false alarmed. I replaced the two there with pi9000 Kiddes. They have worked fine for well over a year. However, not so "lucky" here at main home. I bought 4 to replace 10+ old dual sensor First Alerts. One only is working fine so far ( 1 week). But the other three are failing. They will, after several hours on the 9 volt supply, suddenly drop the voltage in the system, and an ammeter shows they are pulling over 150 ma! This must be what is happening to others folks who are reporting failures. There is some component in these units, not all of them, that is failing. Now what do I do? When not failing, these are the best dual sensor units on the market, but how many do I have to buy before getting the ones I need?!!

I did a lot of research before buying this alarm. I ended up buying two this model and the Kidde 900-0102 both are dual sensor. I placed this model in the basement and the other alarm upstairs because it has a voice alarm that I liked. Each unit installs in a snap!

I never tested this to see if it works (i.e. burning toast, etc...) but the test feature works. I hope to never have to hear this thing go into alarm mode... but if the unfortunate need does arise, I hope this thing answers its call to action!
UPDATE November 2010:
This alarm went off in the middle of the night (no fire/smoke/or anything else)... and refuses to stop alarming. This happened once before, and was easily resolved by cleaning the unit with compressed air. This time, however, compressed air was not able to help, so I'm not sure if it's a dust issue, or something else. This unit isn't even two years old now, so I'm a bit disappointed in it's performance.

I had purchased the 'First Alert' dual sensor alarm (with remote feature), and it gave me nothing but false alarms, some in the middle of the night! Not so with the Kidde. Plus getting to and installing the 9V battery was much much easier on the Kidde than on the unintuitive 'First Alert'. This Kidde dual sensor alarm is the way to go if you want simplicity, ease of use, and peace of mind. I think I am going to purchase a few more now that I know this model works flawlessly.
