I use it for structural engineering design i.e. complicated stuff and it's so much easier to use than non-RPN calculators. I think that I bought my first HP about 42 years ago.

A good machine to have at hand in any engineering related field.\nSpecially aimed at HP nostalgics who don't want/need to carry the HP50g big guns everywhere.\nStill packs a lot of programming power.

Purchased because I've used HP calculators since college (1980) and now can't bare using anything else (RPN). Had 32e and still have 32sII so can have a good calculator at work as well as home now.  As usual with HP it's very well thought out and has the awesome button click. Very very happy

I bought this calculator after my previous one found its way into the washing machine and refused to work again. I am a design engineer and have used HP Scientific calculators for the last 40 years - I think they are very good and wouldn't be without one wherever I am.

This is great RPN calculator at a very competitive price, make no mistake. One thing that could be improved is to attach English leaflet, since the two attached were in German and Italian. However, this lack in documentation does not make the calculator any worse, since proper manual can be viewed from attached CD (or downloaded) and is available in English.

The unit is suitable for practicing engineers, no pointless bells and whistle.It was chosen because it is solidly built and has RPN.. (OK-I'm old!)

Ekomi Review
Based on my initial impressions I am impressed. I use it in my daily work as a chartered engineer carrying out design calculations. Not everything is done by computer even now!\n\nIt is best suited to profesions similar to mine, technical or scientifically based and students studying such subjects.\n\nHaving read some critical online comments I was pleased to find that the quality is very good. It is bigger than my trusty old 41-CX but slimmer and I particulary like the slip case. It'smuch lighter perhaps partly because of the batteries. The key presses and the keys I have found to be good, too early to tell if I will encounter problems with these as reported online.\n\nDisappointed that the printed quickstart guides were Italian and German language versions only, not even an English version on the CD. All the text on the package was in German too. It's not possible to fully exploit the calculator without the manual even if you are used to HP calculators and RPN. I had it printed by an online service and it cost almost 50% of the calculator price.\n\nIn summary, looks promising.
