1) Issues of broken parts with the renewal VF-25's are exhaggerated. I only know of a couple instances where the metal hip bar broke, but the majority of people have no issues.
2) Paint is a bit iffy. Some people like myself are fine with the paint job, but others have indicated Bandai didn't do their best job, such as the white gaps you see in fighter mode where Bandai should have painted.
3) The only widespread problem you will encounter, will be loose joints. It uses the same ball joints as the YF-29 and eventually, the shoulders and legs will go loose. But you can fix that problem with a bit of super glue on the joints. There's a video in the YF-29 thread showing you how to tighten the joints. Works like a charm.
But this really is a fantastic toy. Just gorgeous, and Bandai's best effort so far. (Besides maybe the Hi-Metals. Those were pretty good).
