Both of my Kingsnakes are from BHB. I got them last January. They arrived looking fantastic, and the male still does. The female has a defect in her digestive tract, however. I doubt it showed up noticeably as a baby, which is how I got her, but after having her for a while and trying to graduate her from newborn pinkies it became apparent. She doesn't grow. Both snakes arrived healthy, active, and well packaged.
The two balls I have are from TriReptiles, so I can't say anything about BHB on them, but both arrived healthy. However, I just put a deposit on a Ball from BHB. I don't plan on having her sent to me until next month, after the holiday mailing rush is over, though, so that's no help.
