Well…..can’t give a review, because it hasn’t done anything to review. I haven’t had any gas issues. As far as how it looks and ease of setting it up I give it5 stars.


No thoughts yet, except that it was expensive.

Firefighter family - everyone needs this product!

As a family member of a firefighter, I know how often they get called out for gas leaks and fires. There are several things that I really like about this product that puts them far above the competition.

1. Totally battery powered - which means I can place this where it's most effective, and I'm not limited by a power outlet. So I can hang this up in a high corner of my kitchen, where the gas is going to gather first (Gas rises!)
2. Additional benefit of battery powered - no worries during a power outage
3. Far more sensitive than the products that are available elsewhere today - I'm going to know about a leak much earlier, before it becomes an explosion risk.
4. I can put one in each room - I have a gas stove, gas furnace, gas water heater, gas dryer, gas fireplace, and a gas heater in the garage. So I can easily put one in each room near my appliances and again, I don't have to look for or tie up a power outlet.
5. Set it and forget it - I put it up, and it's good for 6 years!

I feel so much safer with this product in my house!

Also, shipping was super fast, and the purchase process was painless.
