I like how easy it was to use once we got into using cali bera for our needs in calibrations! It's not too complicated but has enough features so there isn't much room left over if needed as well (for me at least).
The only downfall would be maybe some new people who are just coming from other programs may have trouble getting used t them straight away - however this can easily been solved by an experienced user though training/tutorials or guides provided with purchase. We've had great success managing all forms of measurements across multiple departments within my workplace now through calibre series!!
