    This deal has been posted no less than 20 times and seems to be popular each time - does half of OzB live on a boat or am I missing the appeal?

      We can knot get enough of it.

      If youve been camping, use a trailer/ute, go fishing, go boating, like gardening, rock climbing or have kids that go to the scouts. This is great.

      I grabbed it a while ago and it has really been useful. I'll go to tie up a hammock, pull out my phone, bam found almost that'll work.
      It's so basic yet so handy, so I presume anyone that's got it upvotes to keep spreading awareness of the good freebie
