Stop reading and just buy them. They do exactly what they are advertised to do. It seems that a lot of thought went into the design of these instruments. They are durable and lightweight. I put a lot of pressure on them to remove the rear Vstrom tire and never felt like they might slip or break. The inner bead of the tire wasn't scratched that badly and as the title suggests it was my first job on my bike. They were long enough to give me the leverage I needed to get the job done, but not that long. how to get involved. Plus, its compact size makes it easy to stow on my bike for roadside emergencies. I was really impressed with how well the bead separating feature works. I wrapped the end of the spoon in a rag to protect my hands and started working on the tool. I selected points on the rim about 4 inches apart and just pressed point by point a little with some Windex to lubricate until 1/3 of the way around the bead started to slip in the tire. Turn the tire over. and repeated the process. The spoon grabbed the bead well and this is where the longer tool might be a problem. I was able to get the end of the tool under the bead because the tool was short enough not to hit it. I also highly recommend the Motion Pro disc savers. I used them as part of this process and if I hadn't my powder coating shops would be chewing on the beautiful bed.
