Review on CONFAST Concrete Screw Anchors with Phillips Head - Fasteners by James Vilchez

The product itself is not bad. However, I gave it 3 stars because the bit was slightly larger than my Bosch 3/16 hammer drill, which pulled almost all of my first pilot holes out right away. As soon as I switched to my Bosch drill, they all grabbed and threw themselves into my tree. TL:DR - fix the drill and your product will be as amazing as any other brand and at a better price at the same time.
