After receiving this product I was eager to test it because it corresponded perfectly to my needs (small and therefore compact). Unfortunately after testing with a 12V LED strip, you can not make it work (the band stays on). However supplier good prince and of course not responsible for any manufacturing defect fully reimbursed me without demanding the return of the product. I'll take my chances with a more classic product but alas larger (look good presence sensor compatible with LED strips 12V, if you have the same need as me).
