Talk about easy! This roller is SO good for picking up the smallest shards of metal from roofing/siding, etc. and is fast due to the size. Do not hesitate if you are looking for a magnet. The only thing I'd change is that the interior of the wheels were solid for the release action of the metal as often it slips into the spaces--easy to tip the wheel to the side for it to slip out though. AND if you have a square or rectangular bucket for emptying into, this really helps as you don't want those shards slipping through a cardboard box en route to the trash.
