TOPTES CT-580 Portable Carbon Monoxide Detector, Rechargeable CO Detector with Vibration, Visual & Audible Alarms, 0-1000PPM, TFT Color Display for Home, Camping, Travel, Industrial & Professional Use

The product is a little challenging at first, but once you get the hang of it, the sensor does well and picks up what it’s supposed to. It is easy to use and the alarm when CO is detected is perfect.

I tested both meters to great satisfaction. I tested propane gas leak and CO exhaust on a portable generator and wood pellet stove. Woked perfectly. Build quality and design are nice. Color LCD screen are visible and backlighting on-off option conserves battery. Two affordable and desirable safety devices that is would recommend in home, shop, camping and garage.

There are a lot of features I like about this meter. It feels like it is built with quality and could withstand dropping it a few times (although has not happened yet), gives quick results, and it has a nice non-slip cover so you can set it on say a table in your boat and it will not easily slip off. I use it when boating as I have experienced a few times where the backdraft during cruising can cause the exhaust to get into the cabin if the door is open. I cannot attest to the accuracy of the unit as I have not calibrated it or checked against other meters, but the readings seem reasonable.

The product Seems to be solid built ,it works as listed . I would say the price should be around 25-30$ range .seems high but as least product works .

Was worried about my kerosene heater after seeing some videos, so I bought this to use in my small shed when heated by kerosene. Was surprised how well the heater worked, no CO detected. No ill effects and a wall mounted CO alarm also gave the same response. Now I know I can trust my wall mounted CO monitors, but they aren't as portable as this device

It's quite sensitive CO detector. I have tested it on candle, oven, gas stove. Pretty quick response. Another things that are really amazing about this detector are:1. Good battery life! Lasts for 3-4 days.2. You can change low/high PPM level notification.3. It has a journal that shows when CO was detected and PPM level. So even when I am not at home, I still know if CO was detected by checking journal.Overall, very satisfied.

I returned it. Held it directly up to a running tail pipe and it registered nothing. Could've just gotten a faulty one, not sure. Seems easy to use, but I just can't risk something that is supposed to detect odorless fumes which are deadly, to be faulty.

Our furnace is getting old and one day I thought I smelled something coming from the vents. We have combination Smoke/CO detectors, but they aren't inside every bedroom. So I decided I didn't want to risk it and bought this device.0 ppm straight from the vents0 ppm in the kitchen0 ppm everywhere... *except* in the garage!Alarm went crazy when I turned the car on, so I know the sensor works.It gave me peace-of-mind this winter, and I will continue to evaluate and report back any findings.Appears sturdy, seems to be of high quality.
