When installing the battery, make sure the cable isn't under the battery or can't be reassembled. For some reason I couldn't close the device properly. I don't think it interferes with work. On a paper towel, on a metal surface, according to the instructions. Moderately expensive when batteries are included, which should be. I don't know why the battery only lasts a year. I wish you could check (e.g. with a smoke detector) that the battery is working properly.
