I bought these a while ago & I am quite impressed overall. Its the KBC house brand which can sometimes be iffy, but I think this particular set is euro made. Usually I am a tool snob when it comes to drills. I like Precision Twist USA but the price is getting up there. I'm not sure if its the short length, more rigidity or just plain good tip geometry but I think I could have made a continuous chip for 3/4" depth. This is 0.500" drill in 12L14. In hindsight I personally would buy stub length as my first go-to set. The vast majority of times I don't drill anywhere deep enough to justify jobber length, but I guess that depends on your work. But you do get the benefit of rigidity & potential reduced runout if its decent quality. The drill case was nothing to write home about. Most of the numbers are hidden so you have to remove a drill in front to see the value behind it.
