I like them. If you wear Crinklz/Betterdry and they fit you well, then you'll fit these well too. The sizing is the same.
They're just Betterdry with less absorbency, basically. I use them during the workday when I'm not peeing as much. They hold about two or three moderate wettings for me before they start getting uncomfortable and start pressing out at the bum. The biggest benefits are that they are significantly cheaper per unit and more discreet than Betterdry, and they come in larger cases than normal.
If you change at least once during the daytime and like how Betterdry/Crinklz fits, I would give them a shot and see if you like them.
