This caught my attention as the motor (the weight) is at the side of where your hand/body is. So the cutting end should be light-weight, making the tool easier to use, especially as a pole chainsaw.
Interchangeable, 5-in-1 Garden Tool Skin with 230mm brush cutter, 330mm line trimmer, 254mm pole saw, 380mm hedge trimmer and 225mm edger attachments.
These exist in better quality for about the same price, so I'll call this a non deal.
