Fine, you won't listen.

Then how about someone who works with them:

Some of the 6 in. versions and below use the internal barlow [Birds-Jones design] to double the F/L, reduce the inherent aberrations found in spherical mirrors and also enables them to use a 'short tube' design scope. With the 8 in. I replaced the spherical mirror with a GSO parabolic version - with modifications - which made it usable. They are not Synta produced. They came from the 'Fuding Yixiong Co'. [Site below]. They produce most of the entry level scopes you see on E. bay and as sold in departmental stores. The Seben Web site - [Google it] - which is based in Germany but imports these Chinese scopes and renames them and sells them on E. Bay - also advertises model plastic R.C. cars along with its scopes !
Best to avoid.
