Aucanla 12-Digit Desktop Calculator with Writing Tablet - Large LCD Display, Solar & Battery Powered - Perfect for School, Office, and Home Use - Great Math Tool for High School Students, Teachers, and Professionals

This is fantastic. I burn through post-its and have to switch to my calculator app on my phone all the time. This is wonderful. I am very often measuring food, flour, etc. and this is so convenient. I have no idea why this didn't occur to me years ago.It isn't perfect though. There is a slightly raised edge all the way around, so if I rest my palm on it while writing, it feels a bit strange. And the calculator display is a bit hard to read if it's tilted up from your view (like it is sitting on a table, and you are reading it, so you're seeing it at an angle).All in all, I would probably buy one for everyone I know. ☺️I work in an industrial warehouse and I spend a lot of my time having to count up large quantities. I wanted a mobile calculator that I could use to write down other quantities with as well. This WAS perfect. If there was a rating solely for durability I would give it one star. This broke after only a couple of days. It fell from just a few feet and practically shattered. Pieces of the plastic casing went in all directions and parts from the internal circuit board came flying out. It wasn't even fixable. I've dropped my warehouse calculator multiple times and it hasn't even dented. If you plan to keep your calculator at your desk at all times this might be for you. But if you think you may drop it even once I highly recommend buying a calculator with a better quality casing.That it's not solar powered or rechargeableI love this calculator. It is the perfect calculator for machinists. You can draw sketches and dementions while doing your calculations. The only cons are that the buttons could be more responsive and that the calculator can't fold all the way back on its self when your only using one half. With that said I totally recommend this product.I work quality in a machine shop. Sometimes I need to do complex math to check the product from the blueprints. This hives me a writing pad and a calculator without the waste and bulk of carrying a pen, calculator and a notepad in mu pocket. No bigger then my cell phone. The styles snaps into the back cover. The screen erases 100%. I also bought one for my son for his math classes. He has to work evething out and gets lost with all the problems he has already worked out on paper. With this he just erases and starts a new problem. He his 13 and recovering from a traumatic brain injury. The buttons are big but not to big.Bought this for my 4 yr old grandaughter. She absolutely loves it and she takes good care of it (always snaps the stylus on the back so she doesn't lose it :-) It's great for teaching her how to add and the magnetic screen is great.its the perfect size for my needs. the calculator portion is a simple and basic calculator which is what I wanted. But the note pad makes my life easier. instead of having 10,000 post it notes or scratching nots on other pages, I simply jot the quick numbers I need to remember and then use the calc. after recording my final number I hit the trash button to clear the screen. I did accidentally grab my pencil instead of the stylus. it still jotted my numbers down and I did erase the graphite off the screen. even though I don't recommend doing this regularly, the screen did not scratch. or get damaged in my hastened state to jot a coupe of numbers down.Good deal easy to read easy to use the pen bright colors
