Review on 📦 GRK Caliburn XL HandyPak Package CAL1964312HPXL by Jessie Ritchie

They might work in fairly fresh concrete, but they don't fit my fifty-year-old porch. I drilled the pilot holes with the included drill (well, a few holes - the drill wore out after six holes so I had to buy a few more) to a depth of well over an extra 1/2 inch. clarified, blown out the dust and tried to drive the screws. No it does not. You walk half to two-thirds of the way and stop. At this point they will not give in. I've tried unscrewing them, re-drilling the hole with a hammer drill and re-hammering them, but no no luck. Fuuuuuuu. I wish I hadn't wasted my money. I just hope there's an alternative I can use in all those 1/4" holes I've drilled. On the plus side, while these useless scents can't be hammered into very hard concrete, at least none will sheared off from them.
