For those who don't mind scratches on the lens... Please refrain from purchasing if you are looking for high-quality photography. I unearthed this while organizing. I remember buying it new shortly after its release in 2015. I used it for the first two or three years, but then I stopped using it and put it away. The app is still available, but please note that support has ended. Upon checking for the listing, I found multiple scratches on the lens with the shooting button. There's a large chip-like scratch and two groups of multiple fine scratches, one in the center of the lens. (Please note that it's difficult to distinguish between the scratches and the light in the photos.) Regarding the impact of the scratches on shooting, the area with the large chip will usually appear darker, and the rest is not noticeable. The effect of the scratches is clear when near a strong light source. If you are concerned about the impact of the scratches, try turning the scratched side to the back (or?) or the ground. The lens on the back without the shooting button seems fine, but there may be some fine scratches or cloudiness that don't affect shooting. I have confirmed that all functions work. HDMI output, etc., also worked. I have reset the Wi-Fi password and deleted the data. I don't know how long the battery lasts. It goes to sleep in about 1 minute when idle, but this seems to be the specification. It also goes to sleep after recording a video for about 10 minutes. It seemed to last at least 30 minutes (3 videos recorded. The internal storage limit was reached after recording for a total of about 30 minutes). It seems possible to shoot while charging, so if you want to shoot for a long time, you can do so while supplying power. I cleaned it, but there are some scratches and signs of wear, and some color unevenness and fading due to aging and hydrolysis. The color unevenness is also due to cleaning with ethanol. However, the stickiness is gone, and the texture is not bad. Also, sometimes the charging response seems to be poor. A pouch, manuals, and the included USB cable are included. There is no original box. The pouch has some stains. There are white dust spots from the smartphone's sharpening process, but it's not that noticeable in reality. I will wrap it in bubble wrap and pack it with cushioning material and ship it via Takkyubin Compact. Other features: Battery included
