I bought this product for when my little boy was born. I used it for a couple of days and it was great, but then the little switch snapped and disappeared into the unit so that I couldn't turn it on or off. I contatcted the manufacturers and they told me to stick a pin in to turn it on and they would send me a replacement unit. I did as they said and then the alarm went off while we were out (one of the many false alarms)and I was unable to turn it off, which was embarrassing.
The replacement unit arrived and that didn't work properly from the start. It just did not detect the breathing movement so was constantly going off. I had it fitted to the nappy as per instructions and the same as fitted before, but it just would not pick up breathing. It would only pick up pretty violent shaking.
This product was totally unreliable which is unacceptable when it is supposed to be there to help protect your child's life. The people who sold me my original unit had gone out of business and it took a long time for the manufacturers to find another supplier who would deal with a refund for me so I could return both units.
A friend of mine lost a baby to SIDS. I wanted to do everything in my power to make sure that my baby was as safe as it was possible to be. This unit is rubbish. Go for the Angelcare monitor with under mattress sensor and keep a close eye on your baby when he or she sleeps elsewhere. I had a rear facing buggy so I could keep check on my lad and he only slept in his cotbed with the Angelcare monitor fully set up. It's fantastic and I will be buying another. Do not risk you baby's life by relying on the Respisonse monitor!!!
