Flimsy Product Madhu ·
Recommended Not Recommended

Ordered 4 units from Bed Bath and Beyond, Delivery was quick. Opened 2 of them and found 1 has broken "Test' button and second one doesn't work at all. Seeing these 2 didn't open other 2. All of them are going back...



Needs new mounting holes drilled into the wall JED1 ·
Recommended Not Recommended

This was purchased to replace an older C400 unit whose end-of-life alarm signaled replacement need. It was a bit consternating to find out that the new one has the mounting holes spaced about an inch wider than the older edition, requiring drilling into the wall. Also, the new unit uses a much more expensive 9V battery, vs the two AA batteries of the older unit. BTW, the photo on BBY's website is of the old unit, not the newer one.

This is a product everyone should have in their home. Since Carbon Monoxide is an odorless gas you need something to alert you if there is a problem.
