    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 06-12-2020)

    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 20-07-2019)
