Purchased on Amazon. ecoco Gray 100GB. I opened the package once, but it's unused, so it has a capacity of 100GB. I just bought it, so the expiration date is fully intact!!! Due to my lack of knowledge, I no longer need it. I would appreciate it if someone would use it with care. I have never dropped the device, and I have confirmed its final operation before packing. There are no missing items. I will ship it within 24 hours!
