I have Kodi fully loaded, Plug and Play Amazon Fire TV sticks, Quad core media streaming boxes too. Our Amazon Fire TV units require no registration and no Amazon account is needed. All devices are Plug them in, and play units. All hardware is guaranteed, but no guarantee that any particular third party addon software will be working at any particular time as we have no control of that. We include so many addons that it pretty much has any down time covered by another addon.
Once you try these streamboxes, you'll be asking yourself why WHY WHY did you wait so long? People just love them!
