    • Works well if you’re in a well lit area

This calculator is great for simple use. Love the writing pad and feels of solid quality. Not perfect though.. The biggest issues I have are that it doesn’t lay flat when opened and there is no backlighting. If you don’t need those two things it’ll fit the bill for an adequate scientific calculator! Obviously this is not a graphing calculator so the battery is not rechargeable and there is no python programming so if you need that stick with your TI 84 CE plus python or HP prime (you’ll have to wrap in hppl and upload) aka just get a pc and code there lol. As I digress, this is a good value for the price! ... show more

    • Clone of the Casio 991EX ClassWiz, but with some interesting and cool tweaks
Color: 991 ES
First off, this is NOT a review by a "paid" reviewer, or in exchange for a free product I received. I see quite a few reviews in exchange for a free calculator in this listing, so I suspect the company is new and trying to get the word out about their product. This calculator caught my eye because it appeared to be an more feature-rich version of several recent competitor models that have the write/erase slate (the "e-writer") feature. Disclosure: I'm a die-hard Hewlett-Packard calculator collector, so my preference is always for RPN-based calculators, but I do think highly of the Casio 991ES/EX models, and so I decided to take a chance and check out this one. It's possible this is a legitimate re-badged or Casio-licensed version of the 991ES Plus, sold by ROATEE, but I'm unaware of whether it is or is not, so I can't speak to that here. The calculator arrived in a very nice, sturdy box, reminding me of the kind of quality you get from an Apple product. White cardboard, form-fitted, and well protective. Opening it revealed the calculator and a beefy 72 page manual in very good English (I believe this might be taken verbatim from another manufacturer). This was not your typical single page manual like in most inexpensive calculators. The calculator itself appears to be well made and surprisingly thick and solid. I have a couple of other write/erase slate calculators which are significantly thinner, so it's interesting that this one is much thicker (probably about 15cm closed). It is held closed by a magnet, so the slate doesn't flop around like with others. The slate does not flip around the back, so it lays like a book on your desk. The calculator side contains the stylus in the lower right corner, firmly inserted. The top edge includes the battery compartment and the lock/unlock switch for the slate (more about this in a second). I'm surprised at the reviews who say they couldn't find the stylus or lock switch, because both are pretty obvious, and well called out in the first few pages of the manual. An imprinted legend on the back shows the position for the lock and unlock switch. The slate itself is pretty standard. I think the green "ink" could be a bit brighter, but it's very clear in bright light (classroom), and readable in low light, but a bit harder. The "clear" button is mounted on the calculator side as a round button at the top, above the screen. If the slate is unlocked, then pressing that button instantly clears the slate. If locked, then pressing the button does nothing. This is one of the better reasons to get this calculator; most competitors do not have the lock/unlock feature, and it's far too easy to wipe the slate by accident. This will not happen with this model, and it's really a must-have for this category of device. The electrical connection from panel to panel for erasing the screen is via a small copper flex ribbon cable near the upper hinge. It's possible that over time this ribbon cable could wear out and break, but it's super small, doesn't poke out, and it will likely be fine for life of the calculator. The calculator itself is VERY similar to the 991EX ClassWiz calculator, and functionally IDENTICAL to the 991ES Plus model, in terms of button and function placement. For example, on this version the RCL button is the default (face value), while STO is the shifted function, which is the same as the ES Plus model, whereas the EX model has them swapped. Comparing to the ES model, every button is in the same spot. Compared with the EX model, most are in the same spot, although the top row is a bit different. If you are familiar with the layout of either of the 991ES/EX family, you probably won't even notice a difference. Capabilities notably missing from this model, which are in the EX model, are the spreadsheet feature, the graphic "menu" in the mode screen, the super handy "QR" code feature in the Casio [really one of the best and most powerful Casio features!], more screen lines, more memory, and some additional helpful screens and more functions. 99% of the population, including Casio users, won't notice the missing EX features. I did not have the two-left-parenthesis problem with the keyboard that one user mentioned. The keys themselves are pretty typical for this type of product, and work well, with a sculpted edge to the shape of the keys. No missed or double presses, no super wiggly keys, etc. It's not an HP keyboard, but it's decent enough. :) The surface of the calculator is very similar to the EX model, with the textured matte black surface. The key legend colors are okay, but not super bright (the Casio colors are marginally better). Personally, I think the calculator looks very nice and professional, and has a good feel to it. It's lightyears better than the ES family, which has a semi-glossy black surface and picks up fingerprints like crazy. I'm a bit puzzled why it's so thick, given that virtually every similar model is thinner, but honestly, I think I like a bit of heft to it. It feels substantial and robust in the hand. Maybe it's just because of the stylus storage. My biggest complaint on this model is that the manual refers many features to the "Appendix", which is apparently a separate document that was not included. I'm not sure if that was intentional or accidental, but it is a bit frustrating, because some essential information is in there. For example, if you want to use the Conversion feature, you must know which conversion equation you want, by number [1-40]. These are listed in the Appendix document, and NOT in the manual. You CAN look them up online, or refer to a Casio manual, but it's not convenient. Same for the Constants, but at least they are listed by name (not number) in the supplied manual. In the grand scheme of things, this isn't a deal killer, and anyone reading this and thinking about getting it shouldn't be deterred by the lack of the Appendix. Note: the Casio ES Plus lists them on the attached hard cover, while the EX model has a set of menus grouped by function names. On the ROATEE, you're going to have to write down the numbers for each factor somewhere or keep a legend if you use those frequently. Basically, this is a clone of the Casio ES Plus model, and shares a majority of the EX functions. I can live without the Spreadsheet feature, which is honestly clumsy in a calculator form factor, of the EX, but I will always miss the QR code feature. Alas, you can't have everything, and I suspect that feature is copyrighted/trademarked by Casio, which would explain why it's not included. The rest of the differences from the EX are fine as far as I'm concerned, so other than these two small omissions, and the missing Appendix, there is no reason to pass on this calculator. It's excellent for any non-graphical needs, from middle through high school. Price-wise, it's more than the original, but then again you get a cool slate for taking notes and writing down intermediate answers, while still having access to all the same functions you need and like from the original. Overall, I give this a thumbs up, and hope to see more from this company. Especially if they ever would consider producing an RPN edition for all of us math nuts who love RPN. :) Well done, ROATEE! ... show more

    • Great calculator
Color: 82 MS
Bought for my 8 year old with a math obsession. He plays with it nearly as much as his laptop. Took a bit to figure out the pen bc he has misplaced the manual, but after that 🤯! I got it on 25% off discount, so it was a great deal. The numerical readout is a good size with big, fat numbers, so it's very easy to see what you doing. The functions aren't as easy. I wish they lit up or something. I think it's will last, but he is quite hard on electronics. Love the fact that it is a clam shell style instead of that old school slide over. I'm hoping this will add to it's viability. We shall see. I was not paid or given anything for this review. Hope it is helpful. Cheers! ... show more

Got this for my son, but he had difficulty using applications as did his professor.

    • It’s a calculator
Color: 82 MS
The media could not be loaded. Positives it’s a calculator it does everything it’s supposed to do and it’s great for middle school high school and maybe college who knows. It’s solar, so you don’t need batteries for the calculator part. Negative The stylist is tiny and difficult to get out. The fact that you write on one side and it does not transfer into the calculator, makes no sense on why they have that on one side. Children are going to get confused with the lock mode on the top of the calculator. I think some adults might get confused too. The fact that it needs screwdriver is for glasses is another Inconvenience. So I wouldn’t classify this as something that a kid like a middle schooler would get used very frequently. I feel like the stylist is going to get lost. Is it a good calculator other than the screen yes… Do I like that? It has a folding screen so that it closes in on itself and it slides into its designated place easily yes… Other than that, I will have to see how my children like it to know whether or not I will be keeping this. I will update once I find out how my kids are doing at school with this calculator if it is useful or not because the one I got it for is in middle school. ... show more
