I bought 3 years ago saw this after a noname has clearly failed. In the belief that with the name Bosch to get a branded product that even his money's worth then, I actually had good experience in the first year. In the 2nd year, the clamping plate that sitting on a M4 chain spans had so warped that the sword of the provided eyelet slipped out, with the result that the saw was no longer usable. About the suppliers, I then moved into a spare part, this time a round tension nut, much stronger. Now bend no longer that clamping plate, but the screw M4x55, with the result that I can throw both now, because the round tension nut no longer goes by the bent screw down. The saw I can not use it again, have 2fm wood lie and now have to buy a new saw, which I do not know again that predetermined breaking points are hineingemurkst here in the garden. I think it is very useful, even if such technical details when buying online would be visible. This saw I can not recommend and warn only every front !!
