There are some considerations to keep in mind. Despite its advanced features, the machine is intended for use in the US at 120 volts, which could be a drawback for international users or those who might need to use it elsewhere. Additionally, while the AIR1800 excels with stretchy and specialty fabrics, those who primarily sew heavier materials may find that it’s not the optimal choice for their needs.
