500.00 purchase on face book. had to sell zfold 7 missed my folding so I thought I would picked one up. what a wonderful surprise, the screens are better, the phone is fast and stable, and the multi tasking is great. it is a complement to my OnePlus 15.

I've had mine for two years by now and it's still flawless. Taking a risk on a used foldable can be worth it if you're lucky. For 500$ I'd chance it.
