Bought as a gift for my crossword mad husband
Would have preferred it to have a thesaurus as well. Not used yet

After quite a bit of research this as a birthday gift for my elderly mum and it�s just perfect.  Although a compact/handheld gadget the buttons on this are slightly larger in comparison to others which make it more user friendly for elderly � not only does it help with word games/crosswords/anagrams  but also several inbuilt games - good value for money and delivery super quickly.  Thank you

I had a Seiko ER8100 which has packed up. I was hoping to replace it but the ER 2100 was the nearest that I could find I really miss the encyclopaedia and dictionary on the ER8100, and its other features which do not seem to be available on anything else. If you can find a similar product to the ER8100, I would buy it immediately.   The Seiko ER 2100 is a poor replacement!

This is the third calculator I've purchased from Calculators Direct - I'm happy with their competitive pricing and attentive service.

As for the product itself, it's the ultimate engineering professional calculator (apart from the HP42s remake of course). Be sure to download the PrimeComm app for moving programs about and a very handy 'offline programming' interface. Apart form the aforementioned it outclasses all other calculators on the market, there's loads of easily accessible programming and learning material for all levels. The battery life on it is a downside but this can be upgraded with a more powerful phone battery - this may void warranty.

I use it for postgraduate study and professionally, even with all the computer programs and processing power a calculator like this is a very uncompromising way to get calculation templates done, no proprietary software or internet required!
