HP 35s Scientific Calculator:
HP 35s Scientific Calculator. For the affordable price versus its quality. I am satisfied with this product.

Great Calculator!:
The HP 35s is everything that we were wishing for over the last 10 year calculator drought: quality display, quality buttons, programability and RPN.

Excellent Calculator and easy to use:
I highly recommend this for any student or professional. It is loaded with features and is very easy to use.

Brings you back to the days of the HP41:
THis is a great calculator. It will remind you alot of the HP 41. The difference is, instead of having "packs" you buy seperatelly and plug in the back you have to actually program the calculator. This is a positive and a negative. Positive by having the freedom to program what you want and negative by the time consumption to enter it all in.
