Anybody have an Airesflex or Aires Automat?

Looking at Japanese TLR's anybody have one of these and how does it compare to other Japanese models like Yashica quality wise? I see there are some with Nikkor lenses.

i have an Airesflex with the Nikkor lens
i have not run film through it yet, but build-wise and feature-wise it is broadly comparable to the lower-priced Japanese TLRs of the day like the early Yashicas

the Nikkor lens is supposedly very good, as you might expect from a reputable optical house, but i have yet to find a Tessar-derivative on a TLR that i found suboptimal.
