We had success with the Malem.

The key for it to work is consistency. Once you hear it go, you have to get to your child and walk them to the bathroom. Even if they’ve already soaked their underwear, pull them out of bed and walk them. It’s hard and will make you feel like you have a newborn again. We set up the baby monitor again so we heard the alarm. You have to help your kid make the connection between peeing and getting up.
We also bought a lot of the lined bed pads. Put them on top of the fitted sheet. Then all you need to change is the pad. Kid can go right back bed with having to change the sheets.
