Consumers also need to choose the features of the sewing machine according to their needs. For example, some sewing machines have practical functions such as automatic eyelet needles, positioners, and lights, which can improve sewing efficiency and accuracy.

You need to understand the sewing machine brand's commitment to after-sales service, such as warranty period, free repair, etc. At the same time, you should also understand the brand's after-sales service contact information and repair process. In addition, you need to consider whether there is a brand-authorized repair center in the local area.

Finally, you can also consider purchasing additional insurance or extended warranty to ensure better protection when the sewing machine fails or is damaged.
