Review on 🔧 Rocaris Woodworking Drilling Countersink: The Ultimate Automatic Tool for Precision and Efficiency by James Wiley

They're actually pretty crappy and I expect they'll wear out pretty quickly, but for what you're paying it's not too bad. To be honest with things like drill bits and such in my job I usually like cheap stuff as I'm usually on a budget and it works pretty well. If I were more professional I would never use them. Some of them have slight deviations in symmetry and fade quickly. With that said. When cutting pine/softwood this is normal and will take a while to do a reasonably good job.
