Great item for home and garden. I took a carcass + battery 3.5A LiHD + charging = 8800. For the money this is a great set. Sawing raw wood and dry timber 50 quite cheerfully. With a saw for metal, I sawed out the lid of a metal barrel (1 mm) - like clockwork. As for vibration - it takes place when the saw is wrong or when the canvas starts to bite. An important point: if you want to work normally - do not save on equipment, buy normal saw blades (I took Metabo saw blades for wood and metal, but any are suitable). Well, do not overestimate the capabilities of the tool - for its class the device is worthy, for more difficult (dismantling) work there are more powerful models.
