I just picked mine up today. When I got home, there was a damaged corner of the sheet metal, but nothing to drive another 30 mins to replace. The charger is very basic, as you would expect from a roll around. The 2 and 40 amp settings can be used continuously, while the 200 amp can be used for 5 seconds with a 240 second break between uses. I am assuming this means you can crank your car for 5 seconds (which in reality is a long time). The unit is pretty solid. The only thing I really found cheap about it is that the wheels are blow molded hard plastic, kinda like tool cases, except a hell of a lot thinner.
Overall, I think it is worth the $60. I would most likely not have paid double that. I still think it is a good deal for $60, even for $80.
And to those who are curious.... Made in Mexico
