The first impression is good. The mount is mostly metal, it's stable and the capacity is good. I bought it down stair to try it out on the road side. I just placed it on the road side.
GOTO is accurate even with solar system alignment, i.e. I pointed it to the moon and let it go! Going to the Mars is fine enough, Saturn was blocked by a lamp post. But the general direction is correct.
In order to see whether it was stable or not, I plugged in a 4mm eyepiece to check with the moon. Focusing was easy, image was stable within one or two seconds. Tracking was smooth and no shaking... Later I realized that it was 312x!
People said this mount is better with the 4" Maksutov than with a 5" SCT, but I found that it's enough! This mount will be used for solar imaging with my Ranger, so I consider it a nice purchase.

On the next night, I tried to use for my solar setup. Yes, I did it at night.
The Solarmax filter makes it seriously front heavy, I've to slide the balance plate all the way to the other side to reach proper balance, but then the rear side will hit the mount base when the scope was pointing up.
I guess I will need to add some weight at the rear side for balancing.
