Exhaust Jack VS High lift

I have always used one I got off eBay for under $100 and have no hesitation in recommending them to anyone.

Given the differences in material construction of the two, and the experience I had with the busted seam, I personally would now never rely solely on an air-jack as my one and only jack for off-road use. Both are great in their own circumstances, and my work related air-jack experiences in the past particularly with trailers and beaches etc. were all good until my own air jack burst. I intend to carry both for anything serious, but if I had the choice of only one, it would now be the High-Lift.
