I'll try to keep this concise. I bought my DD a Lands End backpack two years ago for first grade. She's used it for two years (just finishing up 2nd grade). Yesterday she showed me where the main zipper is broken. I contacted LE and they told me that they would replace it if I felt that the product didn't meet my standards, but that THEY recognize that things eventually wear out with normal use. So, my question: is two school years (not used over the summers) about the average shelf-life for a Lands End backpack? Should the zipper have held up longer? My DD isn't particularly hard on her stuff. In fact her backpack from Kindergarten which we purchased at Target is still kicking with no broken zippers. Should I make use of the 100% satisfaction warranty or am I pushing it? I don't want to be cheap, and I can certainly afford to buy a new backpack, but I'm thinking if the zipper blows out that quickly I may purchase from a different company next year. I had one (non-LE) backpack for 4 years of high school with no problems! Sorry, for the novel and thanks in advance for your opinions!
