I spotted this one at Linens 'n' Things on Friday. It's a battery-operated grill brush. For $20. Plus the cost of the batteries: eight AAs, not included.
Excuse me, is it that difficult to move a grill brush back and forth? Barring major mobility issues, are you so friggin' lazy that you think this is a good gadget to have in your barbecue arsenal?
Not to mention willing to put more batteries in the landfills.
