    Rated 5 out of 5 by from Audio Quality Also adding to my previous review, the audio quality is excellent. For audiophiles out there the quality using but headphones and external speakers such as car audio systems, stereos, surround systems and PC speakers the sound is flawless. The AudioWizard app build in really helps too.

    Rated 5 out of 5 by from Worth every penny! Considering the price paid for the device and the features offered, it is an excellent investment. Fast and easy to use without delay to perform the functions. Featuring 128GB of ROM and 4GB of RAM plus the good processor makes the phone the best in the price range. I recommend.

    Rated 5 out of 5 by from Incredibly awesome phone... I have been pretty please with this phone. There are so many features (dual sim card, 128 gb storage, phone's performance). It does not have a lot of bloatware like other unlocked phones and get updated pretty frequently. So far... I haven't had a problem with any installed app; it is able to load them pretty quickly. I guess that my only complain is that it heats up a little when using Google Maps.

    Rated 5 out of 5 by from good phone The phone is very high quality. And its back cover is not just beautiful, but nice holding. all the programs that I use work very well. Nothing slows down. I am pleased with your purchase.

    Rated 5 out of 5 by from Great connection I love this phone and I replaced a Samsung galaxy s5 active.
    Date published: 2016-04-19
    Rated 5 out of 5 by from Great Phone This was the best phone that I've ever had with 128 GB built-in and a 200 GB Micro SD card (making 328 GB total storage) what more can I ask for. Intel Atom CPU and 4 GB of RAM means it's fast and never lags.
    Date published: 2015-11-30
    Rated 5 out of 5 by from I'm Very Satisfied Okay, so nobody really needs this much built in storage. Or the shiny silver back. Or in my case with the Special Edition, a second back (carbon fiber). But now I'm spoiled. I would prefer fewer ASUS apps, but at least they are nice enough to let you HIDE the ones you will never use.
