For now you can find the Asus ZenFone 5Z for $ 499.99 on Amazon and Newegg. The Asus online store and B & H Video should also sell the smartphone, but for the time being it will be sold temporarily or in the future.
Another thing that deserves to be mentioned is that the American version of the Asus ZenFone 5Z comes with only 6 GB of RAM and 64 GB of storage space, which is not bad at all. An improved model with 8 GB of RAM and 128 GB or 256 GB of storage space. Of course the price is also slightly higher, but customers in the United States do not yet have the option to choose between the two models.
