I've had my machine since the 1980s; purchased  from an Incredible Sweater Machine TV commercial and purchased later extension additions at a Hill's or Woolworth Department store in Ohio using a newspaper coupon, if that gives you any idea of how these were marketed back then. I have  added non-Bond brand accessories to it over time. It works as well today as it did then, though I have replaced about 10 needles in that time period, did remake the cardboard templates using picture framing/matting supplies, too. Some accessories I use now were for other more readily available and electrically operated knitting machines from the 1970s and 80s, others were just found items here and there, ie: claw and hem weights, since I need more when I added more extensions.

I used mine mainly to make large shawls and blankets or to make hats for homeless, hospitalized and dying veterans and for seniors in nursing homes. It was the fastest, easiest way to do that for me, since I needed quick, easy and fast designs that always work and can easily be duplicated when teaching others to do this. I am a volunteer now and travel frequently for my work and with my family, and am studying to go back to school. My focus now is on fast scarves and hats for my family, lap blankets and things like cat/dog beds for friends and family and  the occasional blanket for my elderly mother. I also make quick hats for the homeless, and baby blankets for friends. If you yarn bomb large objects, this machine is great for that, too.

I leave my machine set up at home in my craft room, and the most important things I can say to assure success with this most basic, simple, manual machine are the following, all of which are discussed in the instruction manuals, the old videos and in the online groups dedicated to this machine:

If your floor or your table isn't level, you will not be able to use this machine. Fix that first. Use a long carpentry level, add shims, carpet under the table or its legs, etc, if you need to.

Lubricate the machine often. It's like using a shredder, sewing machine or car engine: moving metal parts need to be able to slip against one another, not rub and catch. Lubrication is key to that happening, so do that second and do it regularly.

Use claw and bar weights of the proper strength and size, in the proper places, as you move along in your work. Move them up as you progress row by row, or add more as you make your pieces longer or wider. If you don't weight the hem or the piece itself as you work, stitches will not knit, they will drop, become irregular in size, etc.

Always make sure the carriage is properly attached to the bed, so that it properly moves across the row of needles to open and close them properly. If the carriage isn't on properly, the machine won't work.

Tutorials online can show you how to get started and stay on track. It's not computerized and is non electric, so no power source is needed and there are no complicated skills needed to learn to use it. The learning curve, if you've ever worked with crochet or knitting needles or ever done a latch hook rug, should be a short one. This machine and its ins and outs don't take too long to learn, if you are patient and pay proper attention to keeping it level, lubricated and use weights to keep the tension consistent.

If you wanted to, you could box it up and take it with you in an RV or to a second home. I have never tried that.
