CUSTOMER REVIEWS

Truly Amazing

This calculator will do any and everything you need it to do.
It takes a bit of learning to get the full use of it, but after that you're good to go. I wouldn't buy anything less than this product.

Does NOT support Mac OS 10.5 and up!!!

If you only use Mac OS, do NOT buy this calc if you plan to update the calc or upload new programs. It does NOT work and Ti has failed to support the last 2 versions of OS X.
