I have two sets, 7 & 7 Plus. They were sent from the USA and I kept them after using them. They are in very fresh condition but I am not using them anymore, so I will sell them. You can check them thoroughly, there are no issues. I had kept the 7 phone after changing the battery, so it has swollen and can be seen from the outside. If you wish, I can change the battery, or you can do it yourself.
