In my defense it was a LONG time ago. We all make mistakes... I only kept it for a few weeks. My old truck leaked so I needed something disposable. I brought it back to the seller and got my $40 back. Besides, it was only a cabinet it shot, not my couch! Oh, and a school book caught the stinger after it went through the cabinet door. Talk about textbook expansion! It was interesting going to class after that...
