I am the owner of the above mentioned desktop Aurora calculator which I use exclusively for work. I didn't choose the make and model myself as I found the calculator in our store room.

To be honest I am not all that familiar with the big boys in the calculator world and I hadn't heard of Aurora before but this seemed to have all the functions required for my use which is basically the four main calculations of addition,subtraction, multiplication and division and in these respects it seems very adept. (Although it would be a major flaw for a calculator that struggles with its time tables!)

Whilst I do give the calculator quite a hammering in terms of hours of usage a day it seems to have stood up to the punishment quite well although there is a small problem with the buttons sticking or not registering which can be quite annoying on longer calculations, especially when I have a client on the phone. However I have also dropped it a few times and stood on it a couple which doesn't seem to have upset the hardy little fellow.

The buttons are a good size making it difficult for my plump digits to hit the wrong key and the keys are also laid out in a logical fashion making calculations faster.

The calculator has a memory function which I rarely use and a specific mode for calculations in cash denominations which I could see would be quite useful if I had bothered to learn how to use it, so sorry about that but I can't review this aspect with any honesty!

Don't purchase this calculator if you require a scientific calculator with Tangent, Cosine and all the other weird symbols that confused me as a schoolboy, it doesn't have them. If you need to do a large number of calculations on a daily basis and occasionally do a bit of rude word writing in upside down numbers that it could well be up your street.

Amazon will send you one for £12.71 but send me a message and I'll see if there are any left in our storeroom.
