So far so good, although I haven't had the luck other users have, we have been using it for four weeks and he is going less but has not stopped. We are down to wetting once a night and it is usually around 5am. Just have to get him to 6am and then 7am...... Good product loud and vibrates, wakes him up with the vibrations and I wake up with the sound.
