I would of gave 5 stars but there were scratches on 2 of the 3 suitcases. The two larger sized ones. The zippers move smoothly all around. Locks function properly. Casters seem to be sturdy and quiet when rolling. This looks like an all around well built suitcase. If it weren't for the scratches I would of marked that 5th star. We all know luggage looks great out of the box so Ill see how it holds up over my next trip. I am not that concerned with the scratches since its luggage and is going to get all scratched up upon use. Hopefully Amazon gives me a little credit. With all that being said and just unboxing it with out use, I would recommend. I will update review at a later time.
