Amazing product
Took me a while before I purchased. I wanted to do my research first. The reviews of many alarms were that they had false triggers, stopped working after a week and the mats weren’t really ideal if children moved off them at night. I’m so relieved I bought this alarm. My daughter started 3 weeks ago and is now on her 4th night dry. This is a big deal for us. She is such a deep sleeper she didn’t remember the alarm going off through the night or even going to the toilet and having to change into dry clothes. Last 4 nights she has woken up to go to the toilet by herself before the alarm is triggered. Would give it 6 stars if I could! (Posted on )

Great product
We have an incredibly deep sleeper. Whilst this is not perfect we are making some progress so we are happy with the product. I actually wish it was twice as loud!! (Posted on )

My 7 yr old son has now been using this alarm for almost 3 weeks and out of that time we have had 12 dry nights all in a row! He is so excited and its so good to see him feeling more confident. I wish we had gotten this alarm earlier. We will still continue to use it for a while longer yet as suggested but he is well on his way. Very happy! (Posted on )
