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.

Slow support
Color: Green, Size: 15"x15" 8 in 1
Seems to work ok. It is lighter than expected which is a plus. Support is very slow from company and did not come with instructions. You have to email them for a pdf copy.
