I give this product 5 stars because it performs flawlessly. I have been using Otis cleaning products for about a year now and these patches meet all my expectations. When coupled with the Otis bore solvent and brushes I can get my barrels spotless with only a few patches, maximum,I really enjoy that one patch can be used six times. This product even comes in a clear plastic, reclosable container that can be reused afterwards.I recommend these to anyone who asks.
