I recently bought one of these mounts and it is very nicely made. It is basically a 2" / 50 mm Teflon disc mount, about the same size as the TS AZT6 but with an easily accessible, top-mounted azimuth knob. It uses plain bearings and apart from some internal washes is made entirely out of machined aluminium alloy. I guess some would like to see roller bearings or some such, but there is no room for slop anywhere in the AZ baby's design and everything fits together very snugly.
This mount has actually been around for over 10 years, and is machined by the Liu Xiaoyi brothers in China, who used to sell it direct as the Astroslew AIM. (They also did a version in stainless steel, plus a much larger version.) Now the astroshop seem to be their main distributor, who sell it with a generic but well-made Vixen-compatible dual clamp. (TS sell the clamp as their XL Premium Dovetail for 65€). XL is about right, as it is rather oversized, being rated for 20kg against the much smaller mount head, rated for 4kg.
If it matters, the clamp is now silver anodised, rather than the black shown in astroshop's photo, but the mount is still anodised black. Only Issue I had was that the two M8 mounting bolts for the rail clamp sat a little proud of the surface of the clamp, so I replaced them with 2 M8 stainless bolts that I had filed down couple of mm.
I have found the mount to be very smooth in use, and I have it fitted to a Manfrotto 190X tripod, which lacks the option to set the extension at 90 degrees but is more rigid as a result. It only carries a Tecnosky AC 62/520 (the same scope as the Orion Starblast, Vixen A62SS and Baader Scopos 62 - essentially a Long Perng S520M) but it settles down within a second or so, unless the central extension on the tripod is raised too high.)
It would have liked to test the AZ baby alongside the TS AZT6, which is a bit cheaper, but had to choose one so went for the more 'engineered' look of the AZ baby.
If you want some more reviews of this mount do a search for the Astroslew AIM.
