Are these the best bits available?
No.
Will they cut?
Yes.
Is it worth it to buy cheap instead of a brand name?
In this case, YES!
These may not be the very best bits out there but for the price and quality of them, they are pretty good. If you want to make a few things on the weekends then I would look no farther.
If you are a professional and need to use these bits all day every day, then maybe look for better quality. Then again, I've gotten other brand name bits and they have come damaged or lasted only a few BF before breaking.
As long as the customer service department is still pretty good then you can't go wrong with these bits. Even if they break, I can buy 6 bits for the same price as 1 bit from a brand name company. Stop paying for a name or certain color. Its 2023 and planned obsolescence is in full effect so it doesn't matter anymore, all products are designed to break and not last very long. So might as well save a few bucks and get the cheap set. All the router bits and other products start life in the same factory, it's only the name that changes.
