They connect to each other

[This review was collected as part of a promotion.] As a mom I want to have my house as secure and safe as possible and these smoke alarms help me do just that. They connect to each other so if one alerts all of them sound! I was able to install them myself and the connection was very easy too. They are light weight and average size. You dont need to change batteries as they come with it

Easy to install smoke alarms that look cute as well

[This review was collected as part of a promotion.] Super easy instalment of the smoke alarm. There were six in a box so we added it in different rooms. Once you click the button, it is automatically on so no need to add anything else.
