Ok, i have been lurking on this one for long enough.
I work with nick, and when he first told me about the trolley i thought it was a gimmick, a neat gimmick, but still a gimmick. Then it showed up at work one day and i thought it was pretty handy, then we used it for a few weeks, pushed it to the limits, and saw what it could move. The trolley is 100% not a gimmick, i cant believe the loads that one man can easily move with it. If I did tree work on my own I would buy one without hesitation.
