A booster pad is designed to allow for you to be able to extend the life of a diaper a little longer than it would normally be legitimately usable. A booster pad is designed to allow the liquid that you're releasing to go through to the diapers padding, and once that particular padding has been saturated, then you can wear a booster and the booster itself along with a diaper probably will be taking a full soaking.
When I usually work a regular shift, I do not put a booster in my diaper unless it's necessary. They are helpful and they are very very good if you have to go longer duration without making a change. There is an advantage to it however, because it makes your diaper thicker, but the disadvantages is that when you put the booster in the diaper, it does have a habit of moving around sometimes when you're trying to apply the diaper. So far, boosters have been helpful, and I have them if I need them, and I will use them as necessary.
I haven't had any of them explode, however I have had them be pretty saturated, along with a diaper, when it gets that saturated, it feels like it weighs about 10 pounds however!
Just like they would say for a diaper, your booster is only as good as the product itself. The better the product the more it will be helpful to the person wearing it! this is important because you want quality stuff when you're trying to deal with incontinence, anything less and you might as well not even be wearing a diaper, and a jokingly reset when I was wearing a diaper that couldn't even hold it, and hold at least a third of it, that I might as well just take off this bounty paper towel I had wrapped around me and pee on the floor, because that's what it feels like.
