Sound seems loud enough and they're definitely a quality product. I hope I never hear them, but great piece of mind and the price is awesome for smoke and CO2 detection.Easy to install and they look cool to. Silent, very light, periodic green flash, just to know they're working, is a great touch. Low battery indicator let's you 'never forget' when they need to be changed. Install the included AA batteries (3) and mount. Easy enough. Highly recommend!

We traveled a month in Morocco with this, just to be sure there wasn't a CO leak in any of our Air B&B rentals. We removed the batteries when traveling. Of course since it didn't sound an alarm for the month we were there we can't be sure it was working, but at least it was comforting to think it was. I'll put it up in our home somewhere as an extra monitor.

I do not recommend this product. A thick cloud of smoke filled my kitchen from burnt toast in a toaster. The smoke detector did not make a sound until I came near it with the toaster to set it outside. This product does a horrible job of signaling you well in advance of smoke. Sending it back.
