For work. This is an excellent calculator and my last one lasted 15 years plus before it stopped working. I only use RPL logic and find a normal calculator almost impossible to use. If anyone would like to use less keystrokes on their calculator and be able to do more complex calculations easily this is the calculator of choice.

Sorry to give such a low rating but have to confess I have been disappointed with this product.  I purchased it mainly as a crossword solver but find it a poor replacement for its predecessor TPQ108. I appreciate there are a lot more facilities on this but it would seem that that only serves to slow down the operation and whilst scrolling through the suggested answers it is continuously stopping after 3-4 words on the clock timer.  I find that most annoying.  Also the older model had a much quicker direct entry into XWORD and the use of the same button on the top row to access X was much more accessible. Personally for me this product is disappointing and I do miss the simplicity of the former model.  

product was as expected   but the problem is postage costs plus customs costs which exceeded the price of the article. not your fault blame BREXIT

Good price, good service.
