There is a particular requirement for cutting, and that requirement is that you must begin your cut with an electric saw from the edge of the board that is closest to you. Be sure to let the tool rest between cuts because sawing "on weight" causes a significant amount of vibration, which in turn activates the lock and causes the battery to run down more quickly. The benefits of it include: I decided to purchase it as an alternative to a reciprocating saw, and I am glad that I did so. Firewood, boards, metal, and branches were all sawed and loaded while the guarantee was in effect. Nothing was broken, and the lock continued to function despite the increased weight. Since both saws share the same clamp, I was able to purchase a wide selection of blades from a "adult" reciprocating saw. Then I went out and bought a Bosch SG 2 hand saw, which is also a useful tool because it uses the same blades as the electric saw and allows you to finish cutting even if the battery dies. This is a standard instrument that can serve as an electric saw in addition to its other applications, including usage in the garden. Cons Consists of a non-removable battery; after 20–40 minutes of use, the entire saw needs to be charged before it can be used again.
