We had Cat 9 and loved having it.
We put in our lanyards, extra film, used film, sunscreen, toiletries, etc.
It was great for bathroom items because there isn't much room for them in the bathrooms.
It was also great for items we needed when we would leave the room. We always knew where everything was.
We liked the clear plastic one so we oculd see what was in the pockets.
It wasn't expensive, it didn't take up much room in our luggage, and we used it a lot. I highly recommend it.
