Yes, the flipper is real, but it has some issues where you don't have full frequency as some countries block that kind. The only good thing about this product is to turn off tv's in public and opening doors if you give it a card and no you can't use the flipper for stealing cards as it only takes the card number and date of the card not the cvv. So, unless you want to do those things then it's a great product.
flipper zero is real , the main issue is its for pro guys , as if you are a coder then you can use the 99% of its potential , or if you are a noob then you can just play with it , no too much enjoyment on work
