The ghosting on my Huang 552 is very, very faint at the highest settings. On green, it's more visible than red. At the mid settings I use mine on, there's no visible ghosting.
If anyone cares, I wrote a comparative review of the Huang 552 and a HurricanE 552 a while back. From the couple of Huang 553s I've seen, they seem pretty similar in terms of optics so...
