Too brittle for hardwood
Worked fine on drywall but a few snapped when I tried using them on dense oak.

Perfect for drywall projects
These screws bit into the material instantly. No pre-drilling needed for my drywall setup.

Good value for money
Quality is solid. One star off because the packaging was slightly damaged upon arrival.
