I shouldn't have expected much from the $6 level. Not only has the product obviously been used or previously returned, it has not even been repackaged to look like new. Red arrived damaged and unsealed. So damaged that it defeats the purpose of measuring a flat surface. Not worth going back, disappointed overall. It's definitely worth spending a few bucks more for a higher quality product.
