I use this product to pick up nails for shingle removal jobs. Seems very effective with a strong magnet to pick up nails in lawns and driveways. So far I am happy with this product for the relatively low cost.
Super heavy duty and powerful magnet. Lifted hundreds of nails from our grass during a house renovation. Even picks up tiny bits of broken razor blades that the contractors lost and rusted up metal flakes from decayed pipes. Some of the best money I have ever spent on a tool.
