Compactness, power, maneuverability and speed of the variable blade according to finger pressure. I was looking for a jig saw amateur but well designed and essential - to drive attacks and follow the wood, reducing vibration for precision wind tunnel to facilitate visual guidance during cutting - and easy to handle in a small hand . The product satisfies me very far, to the practical plastic box to store the saw with its blade mounted. Delivery and packaging impeccable as usual.
