Pros - Definitely a more sound sleep experience, not waking fully multiple times a night like before, no grogginess in the morning.
Cons - Still waking briefly multiple times a night, strange, vivid dreams, not going to sleep as quickly as hoped.
Only been on the patches for a couple of weeks, so a full month of use may give a different experience.
They definitely do help sleep, and not groggy or tired in the morning, but not getting the massive benefit I hoped from the advertising.
Time will tell.
