I bought 4 citizen calculators only one of them is original . This particular brand is so popular in the market that they have produced exactly the same replicas where consumers will not be able to distinguish between original and fake . Told my dad to bring one for me and after using it one day I was doing some calculations and just when I saw the brand logo name it was written CITLIZEN .
Told my dad and he replied I bought it from a reputed shop .I have attached a photo of it so u can have a look at the fake model . So guys beware of replicas as there are too many of them. in the market. See the hologram and citizen logo should flash on screen everytime u switch on the calculator . Buy original .
