I work as a contractor and I usually buy them every year when reduced sets pop up in the home store around Christmas. I bought a set from Revain and decided to top up the beats as needed this time. I've used other brands but this set seems to be the best in terms of price/durability. I don't think it's worth buying expensive beats that will get beat up anyway. Yes, these bits will dull and break, it happens, but the fact is they look better for the money than the rest. The only problem is they are too short for pre-drilling cabinet screws.
