    I got my Galaxy A42 5g phone very quickly. It works like it's new but I saved money, which makes me very happy ☺️. I will return again and I tell everyone about Back Market. Their service, the quality of their work, saving money and the planet, etc.

    The cell phone is in good condition in general. However, I bought the black color and they sent me the gray one. Anyway, my father liked it, that's why I didn't return it. Besides, the camera is super weird, I don't believe it's really the Samsung A42 camera. It seems to be very blurry, but because I didn't have time to return it and get another cell phone, I preferred to keep it.

    The phone, cord & equipment that came with it arrived safe & sound. This is a great phone that works like a charm. Just make sure not to overload it or the touchscreen may become inactive. Other than that it's great!

    Well in one word, "IMPRESSIVE"! I must admit, I was a little worried about purchasing a used phone from a site I've never dealt with. Here's the deal: Phone was described as "Good" condition, well in my book it was in EXCELLENT condition. Was as described, delivered on time & as stated. So far no problems what so ever. I will recommend Blackmarket & would do business with them again in a heart beat. Thank You Blackmarket,for a great experience. Respectfully, David

    The condition was excellent, the delivery was on time, and the case I bought before I bought the phone fits perfectly.
