I purchased this when my old calculator died. I like the double entry very much so I can check that I entered amounts correctly. It's easy to use and does everything that I need.

I got one SHARP like 14 years ago and still works fine (see image) but some function keys are starting to fade so I got a new model that looks pretty much like the old model and I hope will last for many years to come!

Arrived on time and in good condition. Delivery was fine. I clicked on the wrong button and it said "Not so great" sorry, the delivery was fine.The calculator works great. More functions than I'll ever need or know how to use but it has just what I need.Great price and fast delivery.

I bought this for my daughter based on it being recommended by her school for her math, geometry and trig classes. So far it's worked quite well. The price-point is pretty nice and she's able to use it for exams and such due to it not being programmable.

This calculator's a great choice for someone looking for a non-programmable calculator that isn't an extreme eyesore. It does all the necessary functions for the class I'm in and its glass screen is beautiful.One thing though: The sliding shell that protects the screen and device. It locks into place fairly tightly which is great; I'm not afraid that it will come off on accident and leave my screen unsafe. But! With this in mind, it also requires a certain amount of pressure to open and it only seems to open if you apply pressure on it a bit. I try to open it with a squeeze to its sides and it doesn't work. Pressure on the top and bottom works.However do not apply pressure to the top of the shell. Since the grooves only go in about 2/5 of the case (the bottom end), the shell can go further into the calculator on upper side than it should. There's no barrier looking the device into place there. Meaning if u apply too much pressure too high up on the shell, it can scrape your screen!It's my first day using the device, second day owning it, and I already have a HUGE scratch that's really bumming me when I look at it. It's such a pretty device that it's disappointing.Maybe I'll buy another for the house to look pretty and take this one for class to get bumped around... Why waste money like that and cry over spilt milk. I don't know, I just like to keep my stuff in good shape and to see it get damaged that easily without me being careless or brutish... It's annoying

Very easy to use!I bought this because I lost my other calculator but soon after receiving this one I found my other one. But i still continue to use this one because it is so easy to use. The sleek design makes doing math fun, kinda.Overall very dependable and I would recommend.
