[This review was collected as part of a promotion.] Geometry Honors teacher said that this is the best calculator! We bought it and he was correct it is so worth the price!

Best Calculator

I bought this calculator from Walmart. It is so beautiful and on the other hand very easy to use. I recommend it if you hate math buy one of them to be fall in love.

Beautiful and easy to use.

[This review was collected as part of a promotion.] The calculator works well and came quickly. It arrived in a protective package, which ensured it was safe in shipping.

Solid scientific calculator

[This review was collected as part of a promotion.] It has an affordable price and the functions of the product allow me use advance functions for math and statistics

[This review was collected as part of a promotion.] great calculator for fundamental engineering exam. It gives answers by pressing just a few buttons. It is much less than TI calculators. Highly recommended

great calculator

[This review was collected as part of a promotion.] Excellent fuctions for math amd statistics and easy to use

Highly recommended

[This review was collected as part of a promotion.] The calculator is super easy to use and is handy. Love it! Best for college students.

[This review was collected as part of a promotion.] It's of very good quality. It was at a very good price.

The screen is really nice and easy to read,  probably about the best I've seen without a backlight. I've used it in some pretty dim lighting and didn't have to strain to read the screen. The buttons are quite sensitive and I have to be careful not to accidentally enter things. If you just brush the keys they will often times be activated, so I think the keys could definitely be improved upon, but it's a minor gripe. 

My only other gripes are that you can't easily see the results of previous calculations like you can on TI calculators. I don't mind the fact that there is no power-off memory, but I really like to be able to see a scrollable 'stack' of calculations as I work something out. You can kinda get this by changing the math I/O setting, but it tends to disappear once you go back to reenter something.

I also personally prefer some things to have dedicated buttons, like pi, which is shifted on this calculator. But overall it's been a great calculator at a great price.

Nice calc
