15x15 heat press review only. I have no used attachments. Upon opening the package, I was surprised to find the press almost entirely assembled. All I had to do was attach the digital control unit which just clipped on, and attach the power cord. Note: I had to go over the entire unit, tightening down all the screws and wing nuts, b/c they were not tightened in manufacturing beyond being slightly \"snug\". When lowering the handle to press a tshirt, the back of the unit flexed backwards, which created uneven pressure which could be seen by the back springs compressing a lot more than the front springs, which barely compressed at all. Any tighter of an adjustment and I was worried the back compression would be too much. So I tested a shirt with a 10\" x 12\" design. I set the control to 328f and 15 sec timer, as per my DTF transfer recommendations, added a piece of teflon between the transfer and the press and clamped it down. Hit start, ding, took the shirt out and let it cool. The transfer came out perfectly. Pressed again with just teflon to cure the print and couldn't be happier. It's a cheaper, hobbyist unit. Time will tell how long it works, but I was impressed and recommend this Heat Press at its sale price point of $169, but I wouldn't pay more.
