Many companies, especially the ones that produce rebuildables and mech mods, release their batches in "runs", like 1st run, 2nd run, etc. Other than improvements, do the earlier-generation runs usually have more value to them? I am curious because every time I go out to a vape shop, and somebody brings out a higher-end mech mod, one guy always makes that "oh wow a 1st run!" comment like it's a Babe Ruth rookie card. Just trying to clarify the significance of it. Thanks.
