Easy to use helpline.
Crosswords, anagrams, dictionary, conversion of various monies etc. This is a wonderful product and comes with a very handy booklet which explains the many functions available (Even I can understand it!). It is a handy size and very easy to use anywhere. If you need any help at all do not hesitate - buy this product, the many and varied functions will help you in so many ways.

Fantastic gift for the person who has everything.
This is one of the best products that I have purchased in a long time. It is compact enough to be carried discreetly in a pocket without being bulky. The thusaurus / dictionary is very good, but what I particularly like are some of the other aspects of this item. Being able to input data and save the info is amazing, especially clothing, shoe sizes and currency converter. For all the people who, nowadays, travel the world, whether on business or holidays, this is a must-have for the journey. Simply input the relevant details, press to save, and retrieve them when necessary. There are other similar, cheaper items in the marketplace, but this item is definitely worth the price tag.

Seiko Thesaurus ER2100
The use of the Seiko Concise Oxford Electronic Thesaurus ER2100 did not get off to a good start! The item is supplied with a battery but on trying to get started it was found that the battery was 'flat', but after making a million pound raid (only kidding) to our local Sainsbury to buy a new battery and the fitting of same the ER2100 burst into life. The ER2100 is easy to use and does what it says on the box. However, although holding a large number of words it does have what I consider a few omissions - for example when looking for a five letter word for 'sword' and inserting a couple of letters already available it did not come up with 'sabre'. There have been a few other cases where this has happened. The words are those that come up regularly in crosswords and are not exactly a 'rare' word which I would not expect an electronic thesaurus to have in its memory. I have been generous with the marking as I consider it nearer to a 4 star than a three star. I used to have an ancient first generation electronic 'Rogets' thesaurus which only very very rarely got defeated to which I am comparing the ER2100. All in all a good little machine but be prepared for its limitations - and have a stock of batteries to hand, just in case!!

Pretty good
This useful little gadget is pretty useful when you're pulling your hair out trying to solve that last clue. There are however, a few irritations: 1) It can be very slow to draw up its list of suggested words. 2)The word bank is quite good, but not as comprehensive as some online sites. 3)The thesaurus frequently fails to deliver. 4) The keys feel spongy and are not always responsive. 5) Navigation is a pain, as it does not seem possible to move between the solver and the thesaurus without having to re-type the word. 6) It would have been better to have an anagram button separate from the solver button. It is a pain to have to keep selecting the type of solver you want. However, having said all that, it is quite a reasonable buy for the money.

Fantastic gadget to aid a child with spelling
Fantastic gadget to aid a child with spelling, letter reversing and tracking difficulty. This helps too if the person doesn't necessarily know the first letter of a word, not always but often. Better than I imagined as there are also lots of spelling games to play alone or with a friend that are actually fun to do. There was a novelty with it to begin with but it has proved the test of time and gone to school every day, come out of school bag to be played with regularly by choice, even taken voluntarily on holiday to be played with. Recommend, as a teacher and a parent. I want one!

Very useful electronice dictionary etc
This was purchased to replace my previous one - same model- which I had had for about fifteen years. Very easy to use and covers everything I need - I do a great amount of quizzes and crosswords so wouldn't like to be without it. Very good buy - price excellent as have seen same product advertised at at least £10 more .... thank you

SEIKO ELECTRONIC THESAURUS WITH LOTS OF USEFUL FUNCTIONS
I bought this in Sept 2019 to replace their older model ER2000 which I have been using for over ten years and which was showing its age. This is very similar in functions but I must say the keys are intermittently unresponsive so you have to go back over it, there is no 'back' key and it seems to take ages when 'searching'. I am a bit disappointed and don't think Seiko have improved this. It seems to be a 2004 model with info taken from sources in 2002 and 2003 - all this is written inside the lid, so obviously there will be more up to date words out there in 2019!! I bought it as it's a good price and deemed a 'best seller'.
