Summary: After I bought the calculator, it gave me problems. The screen turn off several pixels. I can't see always pixel, what it is impossible to see completely the numbers. I didn't like it. I bought and in 3 mouths gave problems. Now this calculator is a headache to me.
Summary: I received it, but my problem is that I order the calculator but I just pick it up. The digital numbers are not showing properly for example you punch a five but the number sign not showing the complete number like 2 -- missing from the screen. I didnt notice it until i got home.
Summary: Haven't had this calculator long enough to give a proper review. But so far so good. I prefer a white to a black background. Easier to see the extra functions above the buttons. On the display, it has dot matrix on top line and solid on bottom line. The solid line is easier to see. But dot matrix seems to be what most calculators are using. All of the four line calculators that I'm aware of use dot matrix. As well as most two line. The buttons work fine.
Summary: I love HP calculators. My HP 48SX Engineering Calculator died a quiet death after 25 years of heavy use. I wonder if HP puts the same quality into their new generation of calculators. No batteries is an excellent option. Would have gotten 5 stars if I didn't have to stare to view the tiny decimal point and commas. An excellent calculator otherwise.
Summary: This is an excellent calculator. I use it as my first choice whenever I have to solve a scientific math, electrical, or general radio circuit or radio wave transmission problem. I bought three (3) different calculators at the same time -- because my older one died unexpectedly -- to prepare for an upcoming FCC Exam. I used it to pass my FCC Amateur Radio Technician, General, and Extra Exams.
Summary: Yes Very good product. - Why you bought it (to help my girlfriend in college) - What you like most about it (convenience and speed of calculations) - What you dislike about it (not yet found something that does not like) - Whether or not you would buy the product again (I will not buy because they do not use more after college) Tks
