XINPENGFA Office Calculator, Solar and Battery Dual Power, Metal Surface 12 Digit Calculators Large Display Big LCD,and Large Button

The basics, like +-/* work ok. Mu button is not functional at all. Easy to read, battery is wrapped so tight, you might not notice that it must be unwrapped prior to installation (minor issue)...The GT and MU buttons are totally undocumented (the GT button works, every time you hit = it adds to the grand total, as it should). The MU button, a total mystery, if it is working, it is not working as it does in other calculators. Could not find any documentation on line. Dual power feature seems to work well. Display nice and big, as are the buttons. That is the best thing about this calculator...and the price is right!

Buttons are tough to press, if you go to fast you might not press a button hard enough to capture it in your totals. the CE/On C buttons should be switched. I am an accountant where I need to calculate numbers quickly. I find myself having to re-enter my numbers because I'm not confident with the machine. If I need to get technically, I go to excel for assistance. Its a basic calculator. I missed the window to return, otherwise I would return it.

I like the calculator and if I ever sit for an exam where a calculator is needed, it should work fine.But for every day use, it's way too small and the keys stick too much. It's fine for backup work or if I need a calculator on the go (which will never happen in my life), but for now, it looks just fine in my desk drawer catching dust.

Easy to use and love the big buttons. I run numbers all day and love this big beast. I’ve bought them for all my employees.

Obviously made in China, this item came with instructions for a completely different calculator. After I finished assembling it, (the plastic did not seem to have been fully snapped together) and looking up some of the features on the internet, I ended up with a nice calculator. Buttons have a good feel and screen is easy to read. A thin strip of what appears to be real metal is used on the keyboard. Product looks like it will last, some quality control at the factory before shipping would be my only suggestion. A good value for the money though.

I bought this for my daughter for Christmas. She works from home and needed a new one for her desk. She loves it. It’s a little bit weighted so that it doesn’t move around and most important the big raised buttons are awesome. She didn’t know I had bought it. She had also ordered a different one from Office Depot, paid twice as much for it and doesn’t like it nearly as much. She is sending it back.

perfect size and works great. I wish the display could be tilted up. But otherwise is just fine.

I was not satisfied with this calculator. Its construction is low quality. The keys feel terrible. They wobble all over the place when pressing them. They act like they could get stuck at any point. The markup (MU) key stuck in the down position when pressed. It took some prying to get it to return to the up position. When the key was depressed and stuck in the down position, it didn't calculate. Basically, this was a non-functional key. The instructions are on the back of the box. They are misleading or incorrect. This is a low quality product. It's a challenge to find a desktop calculator these days. I would recommend looking elsewhere when reviewing this calculator. There are better options. The keys on any calculator should feel right. The keys on this calculator do not.
