We have been using SAMi for a couple of weeks now. The function of the camera has been consistent and reliable. Being able to know I'll be woken up if my son has a seizure is a game changer for him with his safety and health. My only complaint is that you have to have to iPad screen on all the time for the camera to function. They have a "clock" mode, but it still leaves the screen on and sucks 30%-50% of your iPad's battery overnight. So make sure you have a full charge every night, or you might not get a notification of there is movement. The other part that did bother me about this, is that I don't remember seeing any information before I bought the product about needing to leave the screen on all the time. I hope this is able to be improved in the future. All that said, if you plan ahead this is a good product for the safety of someone who needs monitoring at night when sleeping.
