This is the GKD Bubble, a new product from the GKD brand, related to the recently popular GKD PIXEL. It has only been used for testing a few times. I purchased a separate 32GB SD card and installed plumOS on it, then inserted it into the SYS slot, and a 64GB card into the ROM slot, creating various folders. *Please purchase only if you understand this. I will not answer questions or provide support. *Please refrain from price negotiations. *The ROM is not included in the listing. Please use your own. *There are minor scratches on the back from the time of purchase (see photos 3-4). Please DO NOT purchase if you expect Japanese quality from a Chinese product or if you are overly concerned about minor imperfections. *Due to the nature of the product and to prevent issues such as product switching, returns and warranties are not accepted. Please understand. *I am also listing this on other flea market sites, so I may have to cancel the order if it sells elsewhere first.
