I do Like this dash cam for the quality but, I the rear window cam needs to be hard wired in. Also look at the name of the product for a hard wired front cam option as mine did not come with one and the booklet inside the box said the option to buy a hard wire. Overall not bad for the price, just not for me.

the problem i have with the above is it will not stay on all all the time when
driving . i have check the wire and that is ok i have had it hard wired also checked USB lose wire still stops and starts

I bought this to bring with me on my travels as I noticed that carbon monoxide alarms are frequently not found in Airbnbs. The small compact shape and easy portability gives me peace of mind when I'm away. I tested the alarm and it detected levels of the gas pretty quickly, so I feel assured that it works. My only gripe is that the battery life is shorter than the advertised 90 hours. It's also nice that it displays temp and humidity and I have found those readings to be accurate as well as compared to other sensors I have in the house.

I was originally hoping to pair this with my car's head unit over Bluetooth, and that somehow my existing steering wheel controls would work with it. No joy - this unit can only use bluetooth to connect to the phone. Backup plan - connect to the car radio over FM. I didn't realize it, but there is SOME FM signal almost everywhere on the spectrum where I live, so there was always interference. So I hard-wired the unit to my car. The unit boots quickly - about 15 seconds - and wireless carplay works flawlessly. I plugged in the external mic, but it's not working well yet. Carplay has real issues interpreting what I say when I try to dictate texts etc, but I think I need to keep playing with microphone location. All in all, I can use the screen to show maps while navigating, it helps me avoid holding my phone to text while driving, and it's what I wanted.

This is nice. Although I am not interested in the amount of humidity, I am interested in a Carbon Monoxide and Smoke Detector for our Airstream. We checked it out with the smoke and works and if the carbon monoxide alarm is as loud it will be great. It has a nice clear design and it is pleasing to look at.

This carbon monoxide detector is great because of its portability. It is the size of a hockey puck. I like that it is small and I can take it anywhere. It is rechargeable so no tossing away batteries. The screen is nice, clear and very easy to read. I really like the cute emoji status indicator. The temperature and humidity readings are pretty accurate i compared them to my weather station monitor. I have placed this detector in each of my rooms in my house for a few days to test for carbon monoxide and none was found. It is currently in my kitchen. My wife cooks a lot and this device will go off if she forgets to turn on the hood range fans. The battery life is very good. One charge lasted over a week. One thing I did not like about this detector is the round design. It does look nice, but the kick stand does a bad job of keeping the detector upright. When charging the battery the charging cable tilts the detector either to the left or right.

The CEKKIENA Carbon Monoxide Detector is an easy to install and set up detector that provides peace of mind. Accidents with carbon monoxide are a regular occurrence during winter when heating a home.

This carbon monoxide detector is a life saver. Two days after installing it, we forgot to let the windows open a bit at night to get some fresh air and it started beeping in the middle of the night. I had to quickly open the windows wide for the rooms to go back to normal.
I love how simple it looks, but gives you important information such as the temperature and the humidity. Also, it’s small enough to carry around and solidly built to survive drops. Too bad that the battery only lasts a few days, if you leave the screen on. And that it’s designed to be set on a flat surface and not hanged on a wall. It’s pricey too.
