I don't have time to calibrate

The calibration has probably been kept for 6 months, I went to calibrate again, it's my own business. I watched the tutorials on YouTube 7x to make sure I didn't miss anything, changed the batteries. Still no bones. It just shows a 4.0 calibration no matter what and then when I calibrate it to 4.01 and it saves the data it IMMEDIATELY starts to drift in the calibration solution. For $40 I'm really surprised it lasted so long but I can't give it 5 stars for this performance.

Pros
  • Certified
Cons
  • The cable is shorter than other picks
