Great features, but how durable...
I haven't had this very long so I'll update this if this calculator breaks, malfunctions, etc. I bought this for math (algebra, geometry, algebra 2) because it has so many features for such little money. It doesn't graph of course but for everything else it's great. Hopefully the button batteries last a long time - those aren't cheap and the ones on this look like a pain in the a55 to get out and replace. Again, if this goes bad I'll update.

photo in advertisement
The picture in the advertisement is not the calculator I received. It however has the same functions as my orginal calculator that is in the advertisment. This new calculator has smaller buttons and harder to read the written functions on it. I would not but this caculator again.

CHEAP.
Do not waste your time or money by buying this calculator. The buttons were falling off of it while I took it out of its package and it didn't even work. Amazon didn't even ask for it to be shipped back. That's how cheap of a product it was.
