    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
