Also the microSD card MUST be formatted with the FAT16 or FAT32 (recommended) format, you could use any SD card less than 32GB, but the Betaflight can only recognize 4GB maximum. We suggest you use this 3rd party formatting tool and choose 'Overwrite format' then format your card. Also check out here for the recommended SD cards. |

Best paper
Size: 1 Ream | 500 Sheets, Style: Letter (8.5x11)
This is my favorite copy paper. Sturdy, great copier color quality, and excellent value for the money. I also use it for painting, with markers as it does not bleed.

Machine works perfectly.
Color: Lavender, Size: 15"x15" 8 in 1
The machine is great, but I noticed that people that purchased the 8 in 1 as I did received stencils for cups, T- shirts, and caps with theirs and I did not receive any; apparently they were to be included and was not, can you help with is?

Calienta de manera uniforme
Color: Lavender, Size: 15"x15" 8 in 1
Estoy muy satisfecha con esta máquina de calor. Calienta de manera uniforme y mantiene bien la temperatura, lo que ayuda a que los diseños queden con buen acabado. Ha sido fácil de usar incluso para alguien que está comenzando en el mundo de la sublimación y personalización. La he usado para diferentes proyectos y los resultados han sido muy buenos. También me gustó que es resistente y no ocupa demasiado espacio. La recomiendo para personas que quieren iniciar un emprendimiento o ampliar sus trabajos personalizados.
