ASUS ZE554KL reviews

ZenFone 4 ZE554KL 64GB Smartphone (Unlocked, Midnight Black) is rated 5.0 out of 5 by 5.
Rated 5 out of 5 by from Everything I Need and More Coming from a Galaxy S4, I feel like the Zenfone 4 has been a tremendous improvement and has all the features that I would ever need on a phone for years to come. For my needs, this phone is fast, has a large screen, dual sim for when I travel overseas, and ample 4GB RAM and 64GB storage. I am particularly impressed by the battery life. I use my phone a lot for emails, news-reading, and messaging, some bluetooth internet tethering, some video apps like youtube and it still lasts me a little over two days without charge on average. If there is a downside, it would be that the surface of the screen has a curvature on the edges that would create halos when using tempered glass protectors. I will continue to explore options for this.� Overall, I am very impressed by the Zenfone 4.

Rated 5 out of 5 by from As Good as Iphone 7+ I replaced my Iphone 6+ with this phone after comparing specs with the Iphone 7+ and 8+.� This phone has the exact same features and more (dual SIM..) than the Iphone 7+ for about half the price.� You don't get IOS, but Android is pretty similar now.

Rated 5 out of 5 by from Great phone for the budget These days everyone looks at the performance of the phone but no one looks at the connectivity of the phone. Asus makes one of the best phones which are compatible with all the countries sim cards with regards to 4G LTE. Keeping in mind the budget factor. Plus dual cameras, fingerprint scanner etc.
