First of all, I have to make this clear. The mount is not rock-solid. You will have slight shakes and wobbles from time to time, especially at high magnifications. And it doesn’t have the butter-smooth motions of a Dobsonian either.
But, the design is such a vast leap forward from the usual altazimuth, it is jaw-dropping. The attachment to the optical tube is managed with a singular, solid part. The connections are smooth and are supplemented with slow-motion control knobs. The mount is made of plastic, but it is a weirdly sturdy, feel-good kind of plastic.
Although other budget refractors have managed to connect the mount to the optical tube with solid connections, they just can’t be connected to the tripod in a sturdy enough manner. StarPro 70AZ managed to achieve this by creating a tangled connection part to the tripod. And the key point is that there is only 2-3 parts connected to each other.
If there is a problem to be found with the mount, it is the height. The mount is slightly shorter than most. This might become annoying if you are a particularly tall person.
