I carry one on my tractor, and have all the issues everyone else has described.  But it has got me out of trouble too many times to not keep it there..

I bought a  knock off about a  year ago.  it worked  OK, but the upright bent soooo easily...  I assume from the steel quality it wouldnt last long.

So its staying (nearly) as good as new, unused in the corner of the shed.
