I bought two these a couple years back and a couple months ago I received another notifications that the batteries for one of the units needed replacement, again. This unit had now needed battery replacement 3 time in just over a years time while my other unit hadn't needed batteries at all. That's $25 for 8 lithium batteries each time, so $75 in batteries in just over a year. I reached out to google support on May 11th and they ran me through the wringer to test things, reset it multiple times,...
Easy to Setup and Install.
I purchased 1 Wired (S3003LWES) and 2 Battery (S3000BWES) to replace old detectors. All units were well packaged. I installed the Wired unit first and then added the two battery units the next day. The wired unit is connected to my Internet Gateway. The other two battery units are interconnected to the wired unit on their own Private network. All are working as specified. The Wired unit mas manufactured in December 2023. The two Battery Units were manufactured March 2023, which means the units h...

Technology finally defeats the 3AM wakup chirp!
Having a home with 5 smoke alarms clustered in a 15' radius to meet the modern NFPA code, I was rudely awakened from my sound night's slumber one too many times by the dreaded 3AM "CHIRP" from one of my old smoke alarms. When they'd "CHIRP", since they are so close together, you never knew which one it was until you wasted at least 10 minutes moving from room to room waiting for another "CHIRP". No More!!! With a Nest Protect, I know when I turn out the bedroom light for the night that our batte...

Nest Protect
I live in a four bedroom home with a young girl, her two bothers and their parents. I thought the features of the alarm would be very good for this house and family, especially if an alarm was detected and its location was vocally announced. This feature could save valuable time in getting all the children to safety. However, when setting up the nest Protect, I discovered that the only choice for the children's bedrooms was "bedroom". Then I found the "custom" option. I decided to use "be...

Welcome to the Future! Worth the Price Tag, Too.
I recently purchased 6 Nest Protects for my 3 story home. I am absolutely thrilled with my purchase. Here are my favorite things about the product: 1. Easy to install. I'm no electrician, but the directions provided in the box made me feel like one. Turn off power, connect black to black, white to white, attach base, attach alarm. Done. Thankfully, my existing screws from my old smoke detectors fit the base perfectly. Took me less than 5 minutes to install each alarm. 2. Alarm functionality. T...

Check the date of manufacture
I purchased this device after quite a bit of research. Smoke detectors are only good for 10 years after manufacture. Since this is a smart device it will stop working at 10 years. Pro’s include the ease of installation when your have the Nest app, the nightlight provided some light when it detects movement, the unit will notify us of alarms when away from home. Con’s: the unit I purchased was unopened but was already 3 years old. Hence paying full price for unit in which almost 1/3 of its u...

Beware of “old” inventory sold as new
Purchased new, I thought. Box was covered with dust, but I find this the norm at Lowe’s these days. Open for installation, the date on the 10 battery was 2021. Now it’s only a 8 year battery. The 2 years worth of dust should have been a tip off. I returned to the Franklin, TN store. I told the “Head Cashier” at returns the battery in the device was over 2 years old, and suggested it not be sold to someone else. She said it was nothing wrong, but would accept the return as I had the receipt. With...

Peace of mind
I installed 8 of these in my house by myself. I watched the how to install video both from Google and a few on YouTube. I highly recommend to anyone planning to install multiple devices in the same house to watch some videos first. Once armed with the know how, the installation went smoothly. We have a multi floor house and I really take comfort in the fact that these detectors not only tell you there is fire or carbon monoxide but they also tell you where it is. We had linked detectors prior t...

Quiet protection
Our new house has an open floor plan downstairs and a smoke detector in the ceiling between the living room and dining room, with the kitchen just a few feet the other side of the dining room. This created a huge problem when cooking. Almost any kind of roasting or searing of meat would trigger the alarm. This happened almost every day. Finally, I bought the Nest Protect based on two factors: it can be disabled or disarmed from my phone, and it warns you verbally first before going off, which gi...

Nest Smoke & Carbon Monoxide Dector
I purchased six of the Nest smoke/carbon monoxide detector to replace an older smoke detector that was installed when the house was built in 2004. The installation inesrection was straightforward. It only required that I use the black and white wires; so I covered up the red and ground wires since I was connecting to my WIFI. They link via the WIFI using the IPhone Nest application. The neat thing about this detector is that cou can perform regular tests using the application. You can also...
