Amazing Product!!
Our 8 year old son is a very heavy sleeper and had only been dry a dozen or so times in his life.  Our pediatrician recommended the Nite Train-r, and our son was really excited about the idea of the alarm.  He didn't have any problems or discomfort from the pad.  We did have a couple of false alarms, but it just shows you how sensitive the pads are -- meaning that at the first dribble, the alarm will sound.  It took less than 10 days and my son has been dry and wearing underwear every night since -- not one accident!  The alarm only sounded probably 3 out of those 10 nights, and that's all it took for his sleeping brain to get it.  I wish we would have known about this/tried this sooner!  It does seem kind of expensive for what it is, but I figure that we have saved a bundle in pull-ups, and it can easily be re-used or re-sold as used.  All you would need are the inexpensive replacement pads for either male or female.  Amazing product!!
