Good product selection
Good product selection, have some things (e.g. pilot operating handbooks) that not many other stores sell. Customer reviews seem pretty helpful overall. Unlike Amazon mass reviews for product ratings, these seem genuine, which is a big plus. Lead time on some products (e.g. certain headsets) was too long for me, but the situation is understandable. My only gripe is that I wish the product page was more explicitly saying when the product is on backorder, since I only noticed this at the last moment at the checkout page.
