In this review the Premium Commercial 12-Digit Large Desktop Calculator is judged on readability, ease of use and everyday office practicality. It is best for users who need a clear, no-nonsense calculator for routine accounting, household budgeting or front-desk work, with the single biggest reason to buy being its giant clear display that greatly reduces eye strain compared with standard desktop calculators.
