This bit set seems as good as milwaukee, dewalt, bosch, and makita bits, in fact they are so similar I wonder if they are all made by the exact same manufacturer and then the different name brands are just slapped on. The drill bits are solid high speed steel, which means they have flex, which means they wont snap like cheaper bits. Depending on which of the 4 brands you find cheaper, given how they are identical as of this review on 2013, I would go with whatever is cheapest. Even the cases are identical. I have bit sets from every single major company, and I use the heck out of all of them and can't tell any difference in any of them in appearance, application, longevity, nothing. Make no mistake, on cheap sets I CAN tell a HUGE difference, with drill bits snapping on their very first use and dull ends not even drilling into pine (at least not at the speed I'm used to). Also there IS a difference between impact and non-impact bits. If you have one of the popular impact drills, they put high torque on bits and will destroy standard bits, even ones made by one of the above mentioned companies.
Hope that helps!
