My AA model from Panda did have a noticeable mismatch of the two inlet pieces and it looks horrible (diameter was slightly off). Same for the Delta, China Easter and Shanghai Cargo examples I had. It just didn't work for me, the gap was way too noticeable.
On the 2 HX versions I own now that part is absolutely flawless. Sold my Pandas and waiting patiently for new AAs and DALs on the HX mould
