Review on Ultimate Masonry Solution: Concrete Screws for Strong & Secure Bridge Fastening by Mark Adams

These screws were perfect. Much cheaper than the big "famous brands" I've used and incredible when listed together. The only mark against them is that the box they came in was very fragile paper/cardboard that was so damaged I had to put the screws in a new storage case and the drill bit was not included as advertised. It may have fallen out due to damaged packaging but for the price they exceeded my expectations and the bits provided are not usually of the highest quality so probably wouldn't have been used anyway.
