Our posts from the BGR Deals team always save you money, but this one might save your life. The Topolek GEHS007AW CO alarm was an Amazon best-seller used in tens of thousands of homes across the country, but it has been pulled from the site and is no longer available for sale. Why? Because UK-based consumer advocate Which? ran tests on popular carbon monoxide detectors and found that this model failed to detect gas in a whopping 80% of tests. If you have this model, you need to replace it immediately. Get the First Alert CO605 Carbon Monoxide Plug-In Alarm with Battery Backup instead. It’s discounted right now on Amazon for less than $23, so you have no excuse to leave your family unprotected.

Here are more details from the product page:

  • Plugs into any outlet and features battery backup for continuous monitoring of CO levels
  • Loud 85-decibel alarm sounds when CO levels are elevated
  • Single test/silence button for simple operation
  • 7-year Limited Warranty
