Are these proper bits of kits?

This question on this particular CNC router seems to come up regularly. In fact it is the same question I too have asked. Although not a CNCer just as yet (waiting for a build), the general jist of those in the know is that it isn't a great machine. Other threads have pointed out poor assembly and commented on strength of the machine being a bit low. However, if I recall, things got a little heated as one member owns one and seems happy with it. But many others have said to me, steer clear.
