B.S.
We used the Malem Ultimate as well. We definitely recv'd good results. He does still have a rare accident if he is over tired, but it was a life saver. He is almost 9 & was very discouraged about not being able to have sleep overs. Because of his age we helped him with it for the first couple of weeks & then we no longer heard the alarm because he took care of it on his own. The alarm sounds at the very instant of moisture, so he would immediately get up to empty his bladder & then reconnect the alarm to a dry spot on his underwear.
I highly recommend any of the Malem alarms. Good Luck.
As a suggestion to try to save yourself the high cost. Check Ebay.
