The display has a narrow viewing angle so you won't be able to see it depending on where you're sitting. The buttons are a little loose too. I knew both of these things before buying and still went with this one because the color was nice (haha).

Bought this calculator for our middle school daughter. Keys are smooth  easy to use, not sticky or clicky. does everything she needs it to! used it for a year, held up well, and it's still got lots of use left to it!

This was a required calculator for my circuits class in college. Once I understood the majority of the functions on this calculator I could fly through calculations very quickly. It is a very power calculator and well worth the money if you are doing lots of calculations. The multiple registers are great to store intermediate values which is EXTREMELY helpful with some longer calculations.

Works amazingly. Bought this model sharp el531xbgr scientific calculator as my previous one had the screen shatter somehow in my backpack. Feels great and the screen is bright. Would like some solar power somewhere but the battery on my last one lasted around 3 years before the screen... The protector definitely helps as i've dropped it and have it hit a sharp surface on the face of the calculator many times but had the cover on to shield it from most damage.

It works and has all the functions but the way it slides in and out of the protective cover is a concern to me. It rubs against the keys otherwise it's okay.
