Great product for the price. Great to have on hand if your a HVAC technician or even if you just want to check your own furnace.

Good tool for the service guy.
As an commercial appliance tech,this has been a good tool to have on my van. Only had it a few months but have used it a few times,and it seems to work fine. Company guarantees its calibration

"NEVER expose to exhaust gas"...
They don't really make that part clear, pre-purchase. I do HVAC service in Colorado. Nearly every furnace installed here needs to be derated for the altitude. New pressure switches during the install, plus adjusting the gas pressure from the sea level factory setting. To do that, I use a meter in the exhaust to get the lowest CO reading possible while keeping the heat rise high enough to avoid condensation in the heat exchanger. If this can't handle exhaust gas it is useless to me. And, as another reviewer pointed out, it just seems cheaply made. Returned.

Misrepresented, not a good product.
Ordered something that was shown to take flue samples. It wasn't working, it doesn't even work as an ambient co detector. The customer service is a mess . No-one to pick up the phone. They don't give clear answers when finally on the phone. And the guidance we receive is completely twisted. I don't suggest you buy their products.

Seems Accurate, Not Industrial Quality
Make sure that you need something that measures under 1000 PPM. I got this to check forklift exhaust gasses, however, unless you have a pretty new forklift, it's almost certain to be over 1000 PPM. Another note, my first unit turned on the first time and then never worked properly again. If I plugged it in, it would just say charging, but never allow me to get to the menu (even after unplugged). That said, the return wasn't too hard. The unit seems easy enough to use, was surprisingly sensitive, and the vacuum pump portion seemed to be quite reliable.

Easy to use and accurate.
The unit is very easy to use and appears to be accurate.

doesn't work with most of the boilers as the probe head doesn't fit into the fitting tubular's chamber.
