Forgot to mention I have seen reports of minor QC issues with the HAL.
Mostly around Grand Slam, but also with the support struts.
For Grand Slam it seems to be more about carelessness of the factory packing the figure. I have seen him packed upside down in the box and someone reported his Grand Slam was missing his helmet. So it probably isn't a quality of the figure thing, just carelessness with packing the figure.
As for the struts, people have been complaining they don't support the HAL well unless in certain positions. It looks like it is a design issue to allow the struts to move into different positions for firing and transport. To make them move the way they needed to the connection point seems to be smoother so allow that smooth movement, but at the expense of a ratchet joint style strength in firing position.
