I use this for work (payroll) and needed a calculator with HRS and MINs. There is so much you can do on this, so I have a lot to learn.

Great HP classic calculator - nothing like them! Recommended for the RPN functionality and build quality - nearly indestructible.

Not enough details for our use. Wanted a more  advanced solver.

I wasn't  sure with calculator to go for so I called up  and as given some really good advice.

The calculator I picked was perfect and arrived in two days. Very happy with the service I received and recommend this shop.
