Easy to install

[This review was collected as part of a promotion.] Easy to install and set up and gives me extra peace of mind. I like that when one alarm goes off the other sound too which is a great safety feature.

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.

You printed the instructions in such a tiny font that I can’t read the instructions without copying them on a scanner and then enlarging them and print it out. Really stupid.

Dear Customer,

We’re sorry for the inconvenience caused by the small print in the included instructions. We understand how frustrating it can be when the text is difficult to read.

To make things easier, we’ve reached out to you via email with a digital copy of the SD19-W Smoke Alarm user manual, which you can zoom in on as needed for easier reading.

We also appreciate your feedback regarding the font size and will share it with our team for future improvement.

Best regards,
X-Sense Team
