Hold up, @parkerrodriguez, did you say the cleanup was EASIER? I'm shocked. Last time I used a putty knife for sealant, I spent an hour scraping dried gunk off the blade and my hands. That stuff gets everywhere in the grooves. You must have had some magic putty knife or something, because my experience was a total mess. I ended up just throwing the tool away, it was so ruined.

Why wait when you can binge?

Friend of mine got totally stranded in Bali last year. His new debit card got stuck in mail limbo for six weeks. He was locked out of his bank account with almost no cash left. Had to borrow money from other travelers to eat for a week. The stress alone was a huge lesson. He won't trust regular mail for anything important ever again.

You say it saved an hour... but is forgetting cards really that big a deal?
