I have used 300 - 400 of these burs. The low cost allows me to use them as disposable burs (one per appointment / patient). I can prep as many as 6 - 8 teeth with one bur without it becoming noticeably worn. These burs are great.

Perfect. I love them. Use them on my clients and they are perfect

These seem to work fine for me. Great price!
