I’m sure if one looks hard enough there will always be imperfections, but Panda is as reliable as it can get in 1:400. They benefit from not being your average market flooder like every other well-established 1:400 brand (something has to give when so many models are regularly pumped out), and by not overcomplicating things like the “innovators.”
How does Panda take advantage of economies of scale with their modest production runs? I have to guess it is because of the exclusives they produce. It is easy to focus on putting out an all around good product when demand is already guaranteed.
