We had the monitor bought for us when we brought our son home from the hostpital. He weighed 4lb. He was born 7 weeks premature, weighing 2lb 11oz and spent a month in our neonatal unit. Although he was fine, he always had an apnea alarm testing his breathing and so we thought it would be best to be on the safe side and get one for our home. My Uncle bought this monitor from Amazon.
It had proved to be invaluable and given us peace of mind (we also kept forgetting to turn it off!), until our son became 6 months old.
We also had the horror of the alarm going off during the night. Checking he was ok we turned the light off and half hour later it happened again! We checked every connection and his position but all was fine. As he was still in our bedroom I left the light on and watched him. Sure enough the alarm went off again but he was breathing fine. In the end we turned off the monitor and I watched him all night.
The next day I checked the instructions and I then realised it was my son who had broken the machine. It states that the item is very sensitive and not to treat the monitor roughly. My son had been kicking the monitor which was at the foot of his moses basket (still being small for his age he still fitted in his moses basket well). That was the night the alarm kept going off!
My advice is that this is a fantastic piece of equipment and I would recommend it to everyone. Just don't put the monitor where little feet can do big kicks! My son is now in his own room and I'm getting used to life without the monitor - just.
