I bought this calculator for to use towards my studies and future work/internships.  It's a trusty calculator.  The brand is highly known in the financial sector and is often allowed in university courses.  I wasn't allowed to use my TI-83 graphing calculator in one of my finance courses but was allowed to use this one.  It's a smaller version to the professional one and is great to start out with.  It's surprising light and definitely has more of a plastic/cheap feel to it in comparison to it's big brother but I haven't had any problems with it so far.  People/university students will find this calculator highly beneficial for both business/economics and finance classes.  So far I've used it in Managerial Finance and Investment Analysis.  It's used in the field of business/economics/banking/finance/accounting and insurance.  For the price it's of great value
