Bought these as a gift to my parents who travel occasionally - they did not need a super high-quality, high-price set, just enough to get them around a few weeks a year. They are really enjoying the set and the price was right! I would have paid more in the department store for the one large upright than I spent on the whole set.
The zippers are sturdy and the cases appear to be well-constructed. Wish there were more colors to choose from, though.
