I first purchased the slim backpack, but it was too small for my needs. The exchange process to get a regular backpack was very easy and both of the backpacks I ordered came quickly. However, I'm giving three stars because (1) the regular backpack could not be adjusted to be small enough to fit my torso (I'm average height for a woman) and (2) I was charged a $7.00 handling fee for returning. It's disappointing that there is a handling fee for a regular return to get your money back, but not a $7.00 fee if you opt for store credit... very frustrating. If there's a handling fee for a regular return, please just have a standard handling fee for all returns.
