Works very well. Ideal for making your own curtains or simply adding grommets to curtains that didn't come with grommets. Comes with a clear plastic hole guide but I think it would be better if this item came with instructions or more reliable instructions. so the customer knows how far apart the sockets should be. Since there were no measuring instructions included with the kit, I had to use other eyelet curtains I had around the house as a guide to determine the distance between the eyelets.
