good value for the money
Color: Blue
I love it.... I have used almost everyday since it came.... the ease in the loading a hat is great. The quality seems to be good, it doesn't take up much room and looks great. The pressure takes care of itself and I don not have to do anything. I believe the value is well worth the money.

Amazing product!
Set name: Sublimation Printer, Set name: Sublimation Printer
All I can say is "WOW". I was skeptical about changing over from my Sawgrass to another brand of sublimation printers. But now I wish I started here from the start! Not only does this machine cost a good amount less with the same paper sizes and options as my SG500 but the ink is cheaper per cartridge and 11ml larger than the standard 30ml I am use to. Set up was super easy, as well as the connection. My prints are bold, bright, and beautiful. I am amazed! I am thankful that the details in the prints show through no matter what material I am pressing on. As a business owner, I need a good, efficient printer that doesn't cost more than the product I am selling. I can't wait to continue using my machine. I have not run into any maintenance issue and can not speak on anything of that as of now. Attached photos; however, my camera did not do it justice.
