### ⭐⭐⭐⭐⭐ Goodbye BluLab pens
*by J***H on October 24, 2025*

So long blue labs... been using this for a while now. Bought 2 blu lab pens, both showed up dry and failed to calibrate after proper hydration. This pen is tough, reliable, and stays accurately calibrated even when its close to the q4 month QC's. Hopefully i don't need to buy another soon, but i may when the time comes. Easy calibration and the blue backlight is Hella bright!
