the myth that ABS spacebars are "warp free" was always just that, a myth
don't get mad just to be mad
it's just frustrating to me that people are blaming vendors for this
I have Jamon and an older drop WoB that has very good quality space bars (no warp). And looking at other posts, I get it older sets could have warped space bars but quite a few pics also show non-warped bars. but if newer sets have consistently all warped bars (which i cannot confirm), that sounds like an issue. Granted, people without problems will not post, but would be nice if someone in 9009, cafe, etc had good space bars and would post a picture. If the quality range of GMK has moved in the direction of more warped space bars, that sounds like an issue.
i don't think it's an easy fix of just sending replacements. there may be more that needs to be done in their production. and i am waiting for the in-spec guidance which dixie said GMK is preparing. i do sympathize with the vendors cause they are caught between a rock and a hard place.
Finally, GMK comes at a premium. like any business, shouldn't they strive for improvements? If gmk continues to make products for the hobby and the business has been increasing, why not make new molds to fix old legends? They seem ok to making molds for new keys/legends. Why not double check their manufacturing to improve quality when the community reports issues. GMK is not lego, but lego is amazing for making ABS bricks at such a high standard. Would be nice if GMK strove for the same quality (keyword being strove, not necessarily consistently deliver).
