From the site: "The first time you get back a book, video, tool, etc. - Lent pays for itself."

This seems like a questionable remark to me. Who's to say you would have forgotten you lent the item out without Lent? I nearly feel offended as my memory is quite good.

I could see myself using this if I lived in a dorm with a lot of random people who enjoyed mingling in my room and I was a collector of material goods.
