I purchased these calculators for use in a high school math classroom, specifically for their exponential and logarithmic capabilities. They are easy to use (layout is clean, functions and mode changes can be found intuitively). I am specifically pleased by how sturdy the calculators seem -- I expect they will hold up well against classroom (ab)use, and the construction of the lids gives me the hope that students will have a harder time wedging them on the wrong way (a frequent occurrence with flimsier lids). Another excellent feature for classroom use is that the calculator shows the operations and syntax of the entry, not just the answer (which is helpful when students don't know why they're not getting the right answer). They came with batteries (always a plus), and the batteries required are a standard size (AAA), which will be a nice feature when battery replacement becomes necessary.

I ordered these for my class. I received the shipment quickly. they don't feel like the expensive calculators do, but the price is right and they work. Two in my shipment wouldn't work. I reached out to the seller and they sent me a pk of eight to replace the two within a few days of our email. wow. thank you!!! The customer service makes these a very worthwhile purchase.

You get what you pay for. It works well but feels really cheap. One broke after 2 months.

Loved these for my classroom! They're durable and survived being thrown against a wall. The batteries are included but are pre-wrapped in each calculator so be prepared for a tedious task before using them!

They calculate real good.In all seriousness, I got these to lend to some of my freshman math students and they're actually very good and more than adequate.

When you type in numbers, it frequently misses digits. Very unreliable.

My daughter was reprimanded at school for her broken calculator. She needed this for her GCSE. It arrived the next day in perfect condition. It came with the battery and it's suitable for all of her work in class.Just what she needs. Cheap, useful and works exactly how it should.
