Well made, but some work errors.

Processing: The calculator is something jappelig packed on, design is slightly similar to the iPhone 4 / 4S with shiny black back and the rounded edges, also are located on the back of knobs, just as on the still-quality processed, matte shell that you both on the front and on the back.

Handiness: The calculator is very comfortable to hold, the keys have a slightly low pressure point, but that did not bother. What bothers me is that have been installed wrong some keys.

Features: The economic union of an ordinary calculator. On the inside are conversion codes for units that you have entered after you Shift + 8 can use.

Overall in grades 2, the old HP calculators he can not build, but the popular Casio-school equipment.
