Review on 🧰 Cab Screw Powerhead 10-Pack - PK150 by Alan Singh

I am a home remodeler and my friend suggested trying these screws based on his past successes with them. I bought a set of sinkbits and also this set with 150 bits. Includes 2 T20 bits. Within the first 10 screws I mixed up both bits provided. I started pre-drilling deeper and used Dewalt, then Milwaukee, then Makita bits. All bits twisted and broken. Turns out the friend who recommended them had old square head bolts that were sold before they were converted to T20 heads. It's a great concept, but they need a T25 or larger hole in the head because there aren't any readily accessible bits that can pull these bolts out without fail. Don't buy this!
