Summary: Just the right size for a shirt pocket. The removable cover is a bit of a nuisance though. Plus the rounded shape of the back side lets it rock from side to side when on a flat surface. And I really question the modified coke bottle design of the sides. All in all it's a good value for the money despite the ergonomic shortcomings.
Summary: i doesn't stay on long, so i'm half way through totaling up my bills when it goes blank and you lost everything. there is other problem with this calculator, but i won't go into it. just say in my mind its a piece a junk even for it's price.
