    Item arrived on time as promised. It looks and operates like brand new with battery life about 3-days. I could not transfer apps from my old phone due to the age of the old phone but all data (pictures, contacts, etc) loaded in with the sim card from the old phone. Had some trouble connecting bluetooth to my hearing aids but help from Mr Google resolved the issue. I'm a happy camper and satisfied customer

    This phone does not work on the VISIBLE network. It says it's unlocked, everyone agrees that it is unlocked, but it only stays connected to the network for about 50 seconds before it is locked out of the network. We spent too many hours on the phone with technical support on all sides before giving up and returning it. Which is another process.

    "Upgraded" from a A32 moving the fingerprint sensor to the screen is a huge mistake. The sensor on the side button was money, 100%. The screen sensor might work 10% of the time. Very dissatisfied with the phone. I've tried all of the "fixes", none of them worked

    After having my moto g stylus for 3 years, the volume buttons came apart and had to tape it bsck together. I knew it was time for another phone, but i didn't want to spend $300 on something brand new or upgrade to a bigger plan. The phone is exactly as hoe it's described in the description. I will need another phone case, but I really like this phone and it only costed me $156 including shipping. I'm never buying a brand new phone again, I'm sticking with Back Market the next time I need another phone.

    I have always been impressed even when I have gotten fair quality it's been excellent. this time I got Good, to ensure it was better than fair as a future gift for my son. not only is it quite visibly scratched but it is dented. that's usually fair not good quality. and I still never received that for fair. I'm disappointed. the shipping was great. it powers on and works appropriately.
