*Video Script* September 2017, I published: “Scam or Not? Casio FX-570ES PLUS for less than MYR50“. However after recently relizing that it’s one of the most popular post on this website and that I never bothered to finish the post, I’m back. This time, the fake Casio FX-570ES Plus returns in addition to a real Casio FX-570ES Plus. From this point on, I’ll be referring to the fake Casio FX-570ES Plus and the box the fake Casio FX-570ES Plus simply as the fake calculator. Also, I’ll be referring to the real Casio FX-570ES Plus and the box the real FX-570ES Plus simply as the real calculator. To note, due to the delay of publication of this post, both the real and fake calculator have suffered wear and tear since I’ve actually have been using both calculators for over 10 months. I purchased the real calculator from a Popular book store for RM69.99 inclusive of 6% GST. I purchased the fake calculator from Lazada for RM45.90 inclusive of 6% GST and shipping fees. Starting off with the Lazada product page for fake calculator. The product page title was “Casio Scientific Calculator fx-570ES Plus (OEM)”. The pictures featured in the product page included a picture of a Casio FX-991ES and a picture of a real Casio FX-570ES Plus box. Before purchasing the fake calculator, I asked the seller about whether this was genuine, and the seller responded by saying it was “copy original”. Originally, I didn’t know what the seller meant, but now I think I know. It means that it’s an original copy of the FX-570ES if can classify copies as originals. Now you might be wondering why I bought this product. My thinking was that there was a chance that it would be genuine and being that there was apparently only calculator left in stock, I ended up purchasing what ended up being a fake calculator. The box of both the fake and real calculator are quite similar. In terms of dimensions, both boxes are the same except for the thickness. The fake box is a thicker box. The fake box to the left and the real box to the right. Then there is the battery symbol on the front. The real box features a battery icon in a white outline and “AAA” within the icon. The fake box features a solid filled battery icon. Furthermore, the font on the real box is bolder than the font on the fake box. The fake box to the left and the real box to the right. The colour of the two boxes also differ. The real box features lighter colours than the fake box. Also, beneath the bar code, the real box states that it’s made in Thailand while the fake box states that it’s made in China. Opening the boxes also differ between the fake and real calculator. At the bottom, you’ll see a cut out on the real box and no cut out on the fake box. The cut out allows the bottom to be opened easier. The fake box to the left and the real box to the right. Upon opening the bottom flap, we see on the fake box nothing and on the real box something. That something is “RJA531615-002V01″. The J is smaller than the rest of the characters. On the top of the box, the flaps for the real box is more complicated and sophisticated in contrast to the more simpler approach for the fake box. The box also has “163x85x46mm+25” on calculator of the flaps. The real box has nothing on its flaps. Upon opening the box, both the real calculator and fake calculator comes with user’s guides and a calculator. The real user’s guides were loose while the fake calculator had its user’s guide rubber band together. Loose, the real user’s guides to the left and rubber band together, the fake user’s guides to the right. To note, the real user’s guide paper feels normal and its text are sharp. In contrast, the fake user’s guide paper feels powdery and its text are not sharp as if they were photo copied. Both boxes contained user’s guide in 6 languages: English, Spanish, Indonesian, Korean, Chinese, Mandarin and French. However, the fake calculator has an additional two language for the user’s guide: Portuguese and Turkish. Furthermore, for the real calculator, each language comes in a book form while the fake comes in folded form requiring unfolding like a map. Lastly the real user’s guide suggests that the user’s guide applicable models are the fx-570ES PLUS, fx-991ES PLUS, fx-100ES PLUS, fx-350ES PLUS, fx-500ES PLUS, fx-82ES PLUS, fx-95ES PLUS and fx-991 while the real calculator only suggest that the user’s guide applicable models are the fx-570ES PLUS and fx-991ES PLUS. Each manual has a code on the bottom left which the table below showcases. Onto the calculators. You’ll find that the real calculator is wrapped in bubble wrap with multiple symbols featured while the fake calculator is simply wrapped in a clear plastic bag. The real calculator has a plastic bag covering the top part of the hard case while the fake calculator doesn’t. I guess it’s to protect the screen. The small sized plastic bag features multiple symbols. Removing the hard case, both the real and fake are similar however there’s a tiny hump at the top of the fake hard case most likely from injection molding. Tiny hump on top of the fake calculator hard case. The fake calculator hard case to the left and the real calculator hard case to the right. However, the biggest difference between the hard case is the sticker. The fake calculator hard case to the left and the real calculator hard case to the right. Moving onto the calculators themselves. The fake calculator is noticeable lighter than the real calculator . The screen’s and print of “natural-V.P.A.M.” have slightly different colours. Apart from the print of “natural-V.P.A.M.” and “CASIO”, the rest of the print on the fake calculator are less sharp than the print on the real calculator. The fake calculator to the left and the real calculator to the right. Powering the calculators on and the contrast on the fake calculator is lighter than the contrast on the real calculator. On the topic of contrast, cranking the contrast to the darkness settings causes the fake calculator reveals a lower quality display. Also, the real caculator can get to a lower contrast then the real calculator. At the highest contrast. The fake calculator to the left and the real calculator to the right. At the lowest contrast. The fake calculator to the left and the real calculator to the right. Pressing on the buttons, I fail to identify much difference in the feel between the real and fake calculator. While holding the calculator, the fake calculator is noticeable lighter than the real calculator. Flipping over the calculators reveals that the fake calculator has a “CASIO QC PASS 08” sticker over a dimple in the plastic. While a dimple in the plastic at the same position is present, there’s no sticker on the real calculator. The fake calculator to the left and the real calculator to the right. The lettering/wording and symbols integrated into the back also differs between the fake and real calculators. There are many differences between the two, but an interesting fact is that the fake calculator states that it’s made in Malaysia while the real calculator states that it’s made in Thailand. Gentle reminder, the box of the fake calculator stated that it’s made in China. Getting to the internals of the calculators, it’s found that the fake calculator uses screws ideal for wood with a pointy tip while the screws used on the real calculator are thicker, have a flat tip and are shorter. Also the back cover for the fake calculator requires to be ‘unsnapped’ from the front fascia while on the real calculator , the back cover just comes off. Real calculator screw on the left and fake calculator screw on the right. Inside, there are many differences. I’ll let the pictures tell the story. I want to quickly mention that if you try to bend the fake calculator, the front and back of would unsnap while for the real calculator, nothing happens. I thought it would interesting to ask some of my friends about what they thought about the fake calculator. Summing it up, they couldn’t tell it was a fake until I told them what made it fake. Overall, there are lots of differences between the real and the fake calculator, but I would guess that to most people, the fake calculator is just as good as the real calculator.
Very interesting your review. However, I missed any calculation comparing accuracy or speed (calculation) for certain features. Reading sqrt(Exp(Ln (arcSin (Sin (M))))^2), using integers, fractional, large integers, irrational numbers, etc stored in memory M, and comparing results or error messages, might give a first clue in terms of accuracy. Another test could be using integration of an Integral, testing its accuracy and time to calculate. This test in RUclips provided large differences from different makers as Sharp, Casio, HP, and Texas models. But I did not see as a Fake x Real calculator of the exact same model. For instance Sharp uses conventional Simpson’s method, while Casio uses another (non-disclosed) method, which results in very different calculation time for the same accuracy, or different results for the same run-time. I look forward to see if you could make another video covering this functional comparison. Thank you for sharing!
He tell us what the difference between the real calculator and a fake one.. that's it..he mentioned already before he end his video the a fake calculator is good as real calculator..no need to compare the accuracy of fake and real calculator

but my question is. does the fake calculator perform like the original calculator in solving?
No they are not the same bro
I used the two
@@zmrnabil3514 thanks bro! God Bless you. 🙏
Same
the fake one doesn't last long p, that's it.
all that comparison? of boxes and documentation and absolutely nothing about performance differences? Huh

Rare thing about my calc is that the qr bar is looking kinda fake but it is made in Thailand
Thailand and China,my sis used Thai rarely don't fade, i used Chinese one frequently button printing fade but the performance is superb
