I bought this calculator to use away from home, to balance my check book while out & about!! I think it's perfect, big enough for many to see in case your eyes are in need of big #'s!! big enough to see what button your pushing & yet small & thin enough to put in your purse or glove box!! I also got a bag to fit it in & it's handy to find rather quickly, the bag has a drawstring & clip so you can close it & clip it to anything so if your looking for a bag Amazon does sell them too!!! Thanks so much for the large features & thin enough to be put away!!!
