The Huskylock 905 is my first serger, and I have used it constantly, being a seamstress. It has never let me down despite owning it for many years. I have used it to make clothing, accesories, and crafts. I have worked with a multitude of different fabrics, from delicate satin to rough felt and wool and with a few easy adjustments from my machine I have been able to sew them with ease. My machine has only ever needed minor maintenance, a yearly scheduled maintenance with the manufacturer, and a changing of blades. The instruction manual is very easy to read and follow, and the threading process is simple to master. The differential feed has become a must for all my projects to allow an even flow of different thicknesses and types of fabric. The ability to serge my fabric while sewing it is now a must for me, and my clothes have never been better or looked more professional. My only regret about the machine is more due to the manufacturer. It is very difficult to get service from Husqvarna unless the machine is shipped away. It is a very specialized name and not easy to get help with in case of problems.
