Dude.. after watching some videos on wobbles makes my bee look like nothing!! Mine has no issues at feeding time, doesn't do the head shake, doesn't move much at all when it "wobbles" and 99% of the time he is normal. he has a slight head tlt now and then, and once in a blue moon starts looking up and goes back wards for a sec.. then straightens out and is fine.
