Review: Great Learning tool and Crossword Solver - As a learning tool and handy crossword helper, this is great! People say using these machines is cheating..truth is, I would not do crosswords or the like if I did not have such a useful tool. Of course, you can look up on internet now, but there are many occasions when on train or I am away on holiday that I do not have access, so this is the tool to use. It gives you daily facts each time you start it up, and there are some good games, including a Britannica quiz. It solves anagrams and there are different ways of obtaining facts and answers. It is very compact so slips in the handbag or pocket very easily, and it has a nice feel to it - quite solid. I know it is a lot of money but I am very very pleased with it.
Review: Functional machine with fairly comprehensive choice of dictionary, but with inadequate screen contrast and font sizes - This product contains the Encyclopedia Britannica, the Concise Oxford Dictionary and Thesaurus, a dictionary of idioms and crossword resources. I bought this particular model because it has a folding lid which doubles up as a screen on the inside, as well as having a dictionary of idioms which I require for my work. This is the second SEIKO electronic dictionary that I have ever owned - I bought my first in Japan some ten years ago which was stolen a few years later in China. This one is lighter, somewhat smaller and not as well-built or -designed as my previous model although both had similar display screens. The Japanese model had better contrast than this one and the font size was larger. This model enables the user to change the contrast, but the best contrast is set as the default in any case. You can also choose between three font sizes : small, medium and large. However, the large size is still somewhat on the small size due primarily to inadequate contrast. This is why some other reviewers have mentioned that the screen is of poor quality. However, size and contrast are the issues. My Japanese model did not have these problems. The design has such rounded edges on this model that I managed to drop it once and nearly dropped it a second time since it easily slips out of your hand. I didn't drop my Japanese model even once despite using it for several years and only using this one a few times so far. As a summary, I would say the model is adequate as long as you have fairly good eyesight and you take care not to drop it.

## Questions & Answers

**Q: Is this user friendly? I am considering this for a gift for a senior citizen who just wants to type in a word and get a definition & word origin.**
A: easy to use ----------and a-lot easier if you read  the manual     loved the first one ,so i purchased a second unit.

**Q: Does this sound out the words?**
A: This Seiko does not sound words. But it will have all the definitions you need.

**Q: Does the dictionary have derivations**
A: You will get derivatives and origins, for example if you put in "fort" you will see a derivative of "fortlet" and an origin "forte" from ital "strong" Obviously the extent of the descriptions is more limited than a full size dictionary

**Q: is information relating to 2016 included or up to 2015 end of.**
A: The one I have ranges from 2004- 2010 but I got the machine a couple of years ago.
I would expect that the type of question is best answered by the manufacturer.

### ⭐⭐⭐⭐⭐ A good repalacement for the excellent Seiko ER8000
*by M***A on 29 March 2019*

I never thought I would ever be able to replace my marvellous Seiko Er8000 that failed to turn off two days ago. This ER8100 is more complicated but has a wonderful collection of information and challenges containing all that I enjoyed before. It takes me longer to get the answer but worth the wait. Well pleased.
