in line with what I expected, I'm motorcycle mechanic training and biker, I can use it to replace my distribution chain and my secondary chain, several hundred dollars saving perspective. The tool itself is a can basic, it consists of several buttons of different diameters depending on the rivet, however, I prefer to extract a scissor kick over the old string to replace it's faster and I then used me Wholesale indestructible pusher to push the new rivet into the new chain. I was pleasantly surprised at the speed of delivery of my order. There are no instructions for use for beginners so follow the advice I just gave you above.
