I vaguely recall reading that one particular focal length had that issue but can't remember which one. I've had the 3mm and 12.5mm and no issues.
I do find it a bit odd that Bintel has brought this line out now when most other vendors have moved on to other models. The Bintel semi apo 80mm refractor also seems to be a Long Perng model that was offered by others a few years back. Nothing wrong with more choices of course but there may be better options for the money.
