    The phone i bought was labeled as "good", so I was worried of the screen having visible cracks or any sort of damage to it - however, it was in perfect condition! It was packaged nicely, it arrived a little late (but this wasn't the seller's fault at all and when i reached out, they responded quickly to sort the issue with USPS!). Overall, the experience was nice. The seller was nice and prompt, and the phone I got was perfect for how much I spent on it! 10/10 would recommend this seller!

    I am extremely happy with my purchase! The iPad arrived quickly and was packaged with great care. The seller described it as having "light scuffs," but I can barely see any – it's in beautiful condition. The battery health is excellent, and it works perfectly with all my apps. The seller was very responsive and provided all the details I asked for. A truly smooth and professional transaction. I would definitely buy from this seller again. Highly recommended!

    good overall

    camera takes a good quality pictures, x100 zoom is useless, you have to set up your preferred shooting features every time you turn camera on and off.

    Great phone!

    I have been a Samsung Galaxy user for years and this phone does not disappoint. It's fast, offers lots of memory and has a camera I'm enjoying exploring. No regrets here!
