The phone is in great condition. ONE tiny nick in a discreet spot, can't even notice! No scratches on screen or back . Definitely worth the money I spent. Phone works exactly how it suppose to. Another plus was fast shipping. I couldn't be happier.

I purchased a phone advertised as excellent condition and it wasn't!! the top of the screen has a chip and right below it a scratch!!! The bottom of the phone buy speaker and charging port are chipped and scratched...I had no choice but to keep the phone because my previous phone was no longer working...I wasn't going to leave a review but I think you should know that it wasn't in excellent condition but phone is in good working condition everything works as it should...Thanks Nick

Phone is in terrible shape considering this is considered "good." It has several scratches on the screen. Some are so deep I can feel them with my fingernail. USB-C port looks to be in bad shape too. Didn't even try turning it on. Very disappointed.
