[2-Pack] 4in1 Plug in Carbon Monoxide Detector & Natural Gas Combination Detectors CO Gas Temp Humidity with 2.1'' HD Screen & Indicator, Propane, Methane Combustible Gas Alarm,White

Very simple to operate. It feels solid and the display is super easy to read. So far it is working as it should.

Looks nice and works for gas where I have it in my kitchen. Already went off when the burner did not light.

Early to judge but is working well. Small in size and adequate info. I knew it did not have a back up but still ordered for cheaper option

UPDATE: I may have received a defective unit. I'm pleased to say that the seller proactively worked with me get the issue resolved. I appreciate their honesty to ensure we were taken care of and pleased with our purchase.---We have had this unit for about a month. It's located about four feet from our propane fireplace. The color display is great. However, we'll occasionally hear a few chirps from it even while the display shows a green bar and "000" ppm. So it's hard to know if there's a problem with the air or with the display or with the audible alarm. I'm considering returning it because it doesn't instill much confidence. Too bad, because it's a good looking little device.

Small. easy to use.

So far this fall at least 5 people in our area have lost their lives to Carbon Monoxide poisoning. This has made me a bit paranoid about having adequate warning devices. We have a gas stove/fireplace in our bedroom so I wanted devices to check for CO as well as natural gas. This particular device measures gas and is a compliment to the CO detector I already had. Both are located directly behind and under the stove. The unit plugs into a power strip and no batteries are required. These units are inexpensive and easy to operate and give assurance that no deadly gasses are present.

Seems like a quality unit. I’ve been using it for a month. It looks cool!

Very attractive and easy to read natural gas monitor. We have it plugged into an outlet just adjacent to our kitchen. It's very easy to read the status of this monitor even from a distance. When levels are normal, the smallest green bar will flash on and off. The display is colorful and bright. There are buttons to vary the display brightness, test the unit, switch between F and C scales (long press the first button), and turn on and off the audio alarm. This unit also provides temperature and humidity readings. We love the ease of use, just plug it into any outlet and after a short calibration, the unit is ready to go. This is an excellent extra layer of safety for our family. Highly recommend.

Das keine Gerät wird einfach in die Steckdose gesteckt und ist sofort betriebsbereit.Erkenn das Gerät auch nur kleinste Mengen an Gas, wird sofort ein lauter akustischer Alarm ausgelöst.Bei uns sitzt das Gerät direkt neben der Heizungstherme und gibt ein Gefühl von Sicherheit.Dank der gut verfassten Anleitung ist die Montage und der Betrieb mehr als einfach.Optimal wäre jedoch, wenn das Gerät netzunabhängig wäre, dann wer es sicherlich auch für Wohnmobilbesitzer und Camper interessant.

Viel Sicherheit für wenig Geld. Wir sind Dauercamper und haben in unserem Wohnwagen natürlich eine Gasheizung und kochen auch mit Gas. Darüber hinaus sind wir an das Stromnetz angeschlossen. Dieses kleine und auch sehr günstige Warngerät gibt uns mehr Sicherheit. Das Gerät ist CE zertifiziert und erfüllt die EU-Norm EN-50194 für Gaswarngeräte. Der Bildschirm ist sehr deutlich und gut zu erkennen. Die Helligkeit ist einstellbar. Im Alarmfall wird ein akustisches Signal gegeben. Der Warnmelder wird an das Stromnetz angeschlossen. So benötigt man keine Batterien. Dem Gerät liegt eine gut beschriebene Bedienungsanweisung in mehreren Sprachen bei.
