My fingerprint and my sons are fine (work most of the time). I think the issue is, you put in 3 prints so that is all the reader has to match.It matters how you set it up. When you add users, I THINK you have to do it when the door is closed? To make sure the user adds their print like they would if they are trying to open the door when it's closed. Not explicit in the instructions so I will try that. Cause if the door is open when you set them up, they may not have their finger in the correct angle? The reason why I purchased this was to make it easy for my husband, and sadly his fingerprint doesn't work for him. I may need to get something different.I am going to try and remove his fingerprint and do it over. If re-doing it (for the 2nd time mind you) works, i will re-post. I really do like it for myself (I apparently had my hand in the correct angle). Most of the time it works, I do have some issues myself, not 100% and a little bit annoying because if it fails, you have to wait for the green light.so if you are trying to get in the house in a hurry keep that in mind.
