### ⭐⭐⭐⭐⭐ Actually Genuine
*by E***Y on 23 October 2022*

When I first saw this product on Amazon at such a low price, I wasn't sure if it was real or not. Nevertheless I ordered it and it actually was a genuine unused product, with the seal and all. I am very happy with the product and 100% recommend the phone as at this price it is a steal! Note: I did buy from the seller Electronic Hub, so cannot vouch for all the sellers.
