Mediocre sensitivity but functional

The smoke alarm works but its sensitivity is not very good. It will go off only after the room is full of smoke. Alarm volume is good. The mounting plate is not very robust. 3.5 stars. However, you definitely need a smoke alarm in your kitchen and one in your child's room.

Great Product.

I have installed 2 products around 6 months ago & shows the blinking light which confirms the working mode. The product was tested before installation for response and found great in response. The installation & the mounting method is very easy. Recommend for buyers.
