I have not opinions about the tools, but on the small triangle of sanding, which is a good idea, I confirmed its poor quality. The rise in temperature due to vibration just leads to the melting of Picos and therefore makes this completely useless utensil (single use). A shame as it was between the object of my purchase. For the rest of no final stance for the moment. I also confirm the difficulty of storing the set in the box, raising the great support delta c is already easier.
