The heat press came fully assembled and works great. Easy to use and accurate. The hat attachment is worthless. First off, it’s a pain to switch out press for hat press. The bottom off the hat press slides and doesn’t stay in place. It’s near impossible to adjust hat flat to press and you’ll end up bending up the hat and have creases pressed into it. Also, because it’s a swing arm, you have to lighten the pressure to fit over curve of hat and increase to desired pressure once it’s hovered over the hat. Way too much work for a mediocre press on the hat.Overall, love the large press but will be purchasing a separate press specifically for hats.
