Clearly an amateur tool. High oil consumption. It's difficult to press the safety switch of the trigger with work gloves.

It's awesome! Today I cut a log with a diameter of 23 centimeters (after removing the chain guard in front of the blade - it has 2 screws). I give it 4 stars because it doesn't have an oil flow adjustment, so if there is any excess oil in the oil container, it slowly leaks out, resulting in oil stains wherever you store it. You just need to put a little oil, enough for cutting, making sure it doesn't overflow into the oil container, and everything will be fine!
