Review on Enhancing Turntable Performance with Strobe Disc: Tests 33-1/3 RPM and 45 RPM Speeds by Katie Richards

If you have a turntable it is very important to make sure that the cartridge is properly adjusted. This not only guarantees the best possible cassette performance, but also helps protect your recordings from damage caused by mistracking. This leveling disc makes the job easier. If you want to delve down the rabbit hole of different alignment methods, there are downloadable protractors. I've always had trouble getting a perfectly punched spindle hole when printing, so this disc eliminated that user error and made the job easier. A good protractor and a good output gauge should be in every turntable owner's collection.
