Great, just as advertised and quick delivery.

Excellent calculator, excellent service. Would mostly suit someone needing a programmable calculator.

I first encountered HP calculators and the Reverse Polish Notation system at a school 'Physics Club' in 1972, and I have been a fan ever since.  The HP was the calculator of choice in my college years, [there were just four of them, bolted to the desk in the Surveying Department!], and I have used them throughout the whole of my working career as a Civil and Structural Engineer.  The RPN and stack notation are still, in my opinion, the best for engineering problem solving applications.

Great service - small issue regarding payment details which was rectified promptly! I wanted to support this local UK business, rather than simply ordering from Amazon - I would encourage everyone else to do the same! They have a great selection of products. More to the point, this Casio Calculator is great - it was well-packaged and very easy to use! Thank you Calculators Direct!
