4.0 out of 5 stars
It works, 24 Mar. 2014
We bought this for our 5 1/2 year old son. The first one we had didn't work at all and we sent it back, and we had a couple of problems with this one too at the beginning, but I think we got better at placing the sensor - it isn't that sensitive if it's not very close to the wet.
After a couple of nights, my son didn't wake up to the alarm, but it did alert myself or my husband to get up and wake him up (and sort out the wet sheets...)
That said, within 3 weeks my son was dry at night - he has now been dry for over 10 nights and appears to have completely mastered it! So, even with the comments above, ultimately it has worked really well for us and I would recommend it.
