So, I recently found those 2 today, and I'm LOVING them, but a couple problems arise. 1. Shockwave's right arm holding his cannon is really loose. The cannon will just...pull his arm down, hardly poseable. Should I find another one and return him or are most like that? 2. Sentinel Prime is awesome in Robot mode, except his shield. The peg to plus into his hand is really loose for me for some reason. Are all of them like that..or most of them? Also, I've tried for like....a half an hour to try to convert him into truck mode, but the final step when it comes to plugging the panels near the windshield just won't...freaking....STAY! Really I'm just debating on returning them or not or if theres something I'm missing for Sentinel Prime. Shockwave was horrendously rare for me to find, I got the last one at Wal-Mart today.
