No problem.
It looks very good for the money. It's a copy of the jig I have which is the Park Tool 2.2 - probably not as solid ( mine weights 9kg) but nevertheless, it looks much better than anything I've seen before for that kind of money. Mine cost just under £200 so £80 is a great deal if it's as good as I think it might be, for the home mechanic.
You will need to mount it on a piece of wood and I found a really good kitchen cutting board. Park Tools sell a stand for the 2.0 and 2.2 stands that I also have and I think is brilliant, it allows you to change the angle of the jig very quickly and easily, ideal for different taks. You don't have to have it but it's useful and you don't need a wood board if you have it.
If Park Tools has a copy right on their jig which I think they have then I don't think this jig will in the market for very long. This is the first time I've seen one so similar. I'm tempted
