I bought this camera for my 3 year old daughter often nosebleed night. I did not used it every day but I was quite satisfied. Two months later, the device does not work, the evening I filled up and the next morning I found at 3/4 full and my daughter began to bleed from the nose. So I would say that the device is effective but unreliable! 2 months of use (1 day 2 and more!) Very very disappointed!
