I have had this for about a year and just unloaded it onto some poor unsuspecting soul at our annual yard sale. During the time we had it we encountered clogged rakes, missed "material" from the box, and any number of other problems. In addition, it inhaled batteries so quickly that I should have bought stock in the battery manufacturer, and the collection boxes filled with incredible frequency. (And, no, we couldn't use the plug in adapter as we didn't have receptacle anywhere near where the box was stored. We tried moving it, but cats are funny about change...they kept going where it had been previously located.)
