it's a bit wonky. The temperature varies 25-30 degrees as you use it and never hits the exact temp you set, it boomerangs back and forth. The HTV that I use doesn't seem to be adversely affected, so I don't worry too much about it.The vibration is interesting, however it can cause mal-alignment of multiple-layer HTV designs, the top piece slides. So what I do is place the artwork, then put the press on top, lean on it hard to give it pressure, to set the HTV in, before I turn on the vibration and timer. I don't want to use the vibration for dye-sublimation, the risk of ghosting is too high with that.The other thing is, the unit has the place in the cabinet that's molded for the Mug/Hat Press Attachments, but it's hollow and has no such feature. Much literature online talks about that feature being available on the two larger sizes, but it does not appear on this one, so if you need that, know it's not being made that way anymore.
