First Alert GCO1CN Plug In Combination Explosive Gas/Carbon Monoxide Alarm with Battery Backup Review

First Alert GCO1CN Plug In Combination Explosive Gas/Carbon Monoxide Alarm with Battery Backup
Average Reviews:

(More customer reviews)
This is the worst $50 I've ever spent. I HATE this alarm. Although it's plugged into the wall, you also _have_ to install a 9 volt battery. Most devices that have a battery back up don't drain the battery while the unit is plugged in. Not this alarm! I probably go through 3-4 9 volt batteries each winter. And if the battery starts to lose it's charge, or you dare to leave the battery out, the alarm beeps every few minutes.
Another important thing to note about this alarm... although it can detect carbon monoxide and natural gas, you're supposed to mount the device at different heights depending on the gas you're trying to detect. In other words, it doesn't really serve it's dual purpose.
Although I've already lost the $50, I'll be buying a different alarm for this season. I can't take dealing with its battery problems anymore.

Carbon monoxide (CO) is the leading cause of accidental poisoning deaths in America, yet many people don't know they are suffering from CO poisoning until its too late. Since symptoms of CO poisoning are like the flu, you might not even know you're in danger at first. That's why a carbon monoxide alarm is an excellent way to protect your family. It can detect the CO you can't see, smell or taste in the air.
The First Alert GCO1CN combination explosive gas and carbon monoxide alarm uses an electrochemical carbon monoxide sensor-the most accurate technology available. It also detects natural gas, methane gas, and propane gas. Installation is as simple as plugging it in to any wall outlet or mounting it above an outlet and plugging in the higher line cord. Its easy-to-read large digital display gives you a clear readout of current hazard and levels. A peak level button alerts you to the highest level of explosive gas or carbon monoxide detected. The alarm includes a battery back-up giving you peace of mind in a power outage. The test/silence button both silences a non-threatening alarm or low battery warning and allows you to test the unit's functionality. The unit monitors and alarms if carbon monoxide or explosive gas levels persist sounding a loud 85-decibel horn. A low battery signal alerts you to replace the 9-volt battery (included). UL listed. --Bree Norlander

Mighty Mule FM137 Digital Keypad Review

Mighty Mule FM137 Digital Keypad
Average Reviews:

It is nice that you have the option of using this in a wired or wireless configuration. In my case, wireless was the only way to go.
Like other 'programmable' wireless remotes, I expected a little pain in programming this one. The instructions have you press a certain key sequence and hold a working remote close to the unit until it beeps. The manual says it takes a little while. I must be impatient because I held it there for a good long time and it never beeped. But I tried it again and held the transmit button down for a very long time and sure enough, it finally beeped.
Programming access codes is very easy, much easier than other keypad devices I've used.
There is no delay in transmission, either. When I enter my code (I like the lighted button and beep feedback), my gate starts to open immediately.
Mounting is trivial.

Schlage BE365VCAM716 Camelot Keypad Deadbolt, Aged Bronze Review

Schlage BE365VCAM716 Camelot Keypad Deadbolt, Aged Bronze
Average Reviews:

For years we have been using a key pad activated deadbolt for front doors in our various homes - no keys to lose or give to various family members - only four digit codes. Up until now, all of the key pad units we have installed, extend and retract the deadbolt using a small battery powered electric motor.
This issue we've encountered is when the batteries become weak, the motor (in some cases) does not have enough power to retract the bolt and we must revert to another entrance to get into our home. Although these unit allow one to use a key to override the electronics, we never seem to have the key "on us" when it's needed. Fortunately we have a keypad on our garage door and that serves as an alternative entrance when this occurs.These deadbolt retraction failures have been occurring more and more often even with fresh batteries. I suspect the motor is or has worn out.
With this in mind, I shopped the market for an electronically activated dead bolt with manual bolt action. In other words, instead of a motor extending and retracting the deadbolt, one would use a lever or knob to perform this function. The keypad (electronic segment of the unit) would serve to activate the manual knob or lever. I found the Schlage BE365VCAM619 Camelot Deadbolt Keypad, Satin Nickel on Amazon at an extremely reasonable price and it has all of the features I wanted - electronic key pad activation, manual extension and retraction of the deadbolt upon activation.
The unit arrived yesterday and after a few problems with the unit being confused as to whether the bolt was retracted or extended (my fault), the unit works perfectly. Note, I already had a deadbolt lockset on the door, so it was a simple process of removing the old, and installing the new.
It's an extremely high quality unit without the cheap plastic casing my prior unit had on the inside casing. It's all metal. Changing or adding key pad codes (combinations) is relatively easy. One must enter the units six digit master code (don't lose this code, keep it in a place that you can go to each time you wish to change the codes - Using a permanent marker, I wrote it on the inside of the lock), and then enter your personal four digit code. We use two codes however the unit can store many codes. You may want to add a temporary code to let a service technician into your home, then delete that code when the work is completed.
One feature I like is the lighted key pad which our old unit did not have. If we forget to turn on the porch light, by simply pressing the "schlage" button at the top of the keypad, the keys light up.
Here's the basic operation.
When you're leaving the house, close the door, press the "schlage" button, wait for the click, then extend the deadbolt. You'll hear a confirmation click confirming that the locking knob/lever has been disengaged from the deadbolt after the deadbolt has been extended.
When you arrive home, simply enter your four digit code, you'll hear a click, then manually retract the deadbolt and enter the home. I you wish to use the keypad light; simply press the "schlage" button to light it up. Obviously this is not needed during daylight hours.
Basically the nine volt battery is operating the keypad, a knob/level engagement solenoid and the keypad back light and should last for hundreds and hundreds cycles.
Bottom Line - I highly recommend this high quality unit.

Keyless Entry Deadbolt, Antique Brass Review

Keyless Entry Deadbolt, Antique Brass
Average Reviews:

(More customer reviews)
The advertisement on the internet fails to mention a couple of things:
1) The numbers in the combination can be entered in ANY ORDER, exponentially reducing the number of possible combinations. If you choose 2345, you could also open the lock if you push 5432, 3245, any other order of those digits, or if you push those 4 digits simultaneously.
2) The lock as purchased only allows you to choose up to 4 digits for your combination. You have to send away and pay more for the other 2 digits.
