Saw a pallet full of these at Bunnings Ashfield (NSW).
Looks similar to this line trimmer deal but this is $20 cheaper, has wheels for edging, slightly bigger cutting width and slightly faster no-load speeds.
Can't find any information on the Bunnings or Ozito websites, however did find what appears to be the Einhell page
Don't have personal experience with it but would be keen to see if anyone has tried one.

From what I've gathered these are pretty under powered. I've seen neighbours using both and the 36v (2x18v) looks like the way to go. Maybe if you've only got a small patch of grass or area to maintain this might be worth it.
