First scientific calculator full of functions. Excellent aid for my children's study. Very convenient included whiteboard for taking intermediate notes. I highly recommend it.
It's very good, the brightness is not the strongest on the writing surface but it can be used for that.
Versatile bundle of a scientific calculator electronic notepad. Very useful to take annotations or intermediate results. Calculator has a lot of functions and can be powered by internal batteries or by solar light. A good article at a good price (flash offer) = a great deal. Very satisfied with this purchase.
Great product, works as described. It is a combination of a medieval writing table and the most modern technology of the 21st century. I bought it for a schoolboy who is learning to count (on the right side) and checks the result on the left side. Banggood always surprises with something new, I am satisfied with this store.
Nice calculator, very useful and handy note pad
Scientific pocket calculator with separate display. Interesting idea and very useful function. Otherwise just a regular scientific pocket calculator. Fast delivery, solar cell for power support.
