## Customer Reviews

### ⭐⭐⭐⭐⭐ Great Item, Great Price and A Must Have!
*by Y***A on December 26, 2015*

I purchased this item after seeing this item on a shopping channel. In fact, I was about to purchase this item from them knowing the importance of have a CO detector and to get one with a 10 year battery. I thought I could not go wrong but before I hit that confirm purchase button, I decided to check my trusty Amazon and what do you know? I found the same exact item on Amazon for less then the doubled price than that shopping channel was charging. The product is easy to set up because there is nothing to do other than take it out of the box and either sit it on a shelf or hang it from a nail. I would recommend this item as a must have because it is just that important. Your family is just that important.

### ⭐⭐⭐⭐⭐ Good unit

### ⭐⭐⭐⭐⭐ Very satisfied
*by A***R on September 21, 2024*
