This is a new GKD brand product, GKD Bubble, from the team associated with the recently popular GKD PIXEL. I have separately purchased and installed plumOS on a 32GB SD card → inserted it into the SYS slot, and a 64GB card into the ROM slot → and created various folders. *Please purchase only if you understand. 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. *Please "absolutely" refrain from purchasing if you expect Japanese quality from a Chinese product, or if you are overly concerned about details. *Due to the nature of the product and to prevent issues such as product replacement, returns and warranties are not accepted. Please understand. *I am also listing this on other flea market sites, so I will cancel the order if it sells there first.
