Terrible "Excellent" used phone
The bottom line is that this phone had a huge dent on the spine. Anyone that knows anything about these folding phones knows that this is a failure point. If there is a kink in the back of the hinge that should never be classified as even good.

False advertisement
This is the second time that I tried to buy it and happen the same story. I cancelled the first time because they drop the price, and at the same time I wanted to know if I did something wrong. So I cancelled the first order, but I had to do it in the store, and I took advantage and bought it again ( to avoid mistakes) in the store, I paid there and everything, then at the next day I got a notification said the same thing, that something when wrong and the date gave by the website will be move (no date given), and I have to wait 15 days after for them to cancel and send me the money. What I told you the other day is correct, they never ment to sale you anything, they just want to use your money get some profit and then give it back to you. I believe that I am not the only one, think about it, it cost $700 times 10000+- customers equals to $7,000,000 if they invest it and they won 5% of it means they get $350,000 of straight profit.

Refurbished but not to manufacturer standards
Phone came without factory screen protector so it was already a red flag. Hinge has difficulty opening fully and makes a weird sticking sound when opening.
