I was a bit skeptical about this press, but I bought it anyway. BOY AM I GLAD I DID!! I am a professional level designer of tee shirts and anything else you can produce through sublimation. I do not use Cricut materials, I print my own out with a sublimation printer and have purchased blank mugs through another vendor.  I mention this for those of you that believe that only Cricut mugs and inks will work ... that is not the case. Now on to the press....THIS PRESS WORKS WONDERFULLY!!!  My other mug press has to be adjusted for the size of your blank to achieve the proper pressure during the heating cycle...this press adjusts AUTOMATICALLY depending on the size mug you're put inside!!!  I truly love this feature.  So far, I've succeeded at  11oz, 15oz and a 16 oz beer stein with beautiful results. Thank You Cricut    BUY THIS PRESS, YOU WON'T BE DISAPPOINTED!!
