Any idea about this Motorized focuser?

I just stumble upon this Chinese astroshop site and found out that they are selling a motorized focuser for RC8 telescope which is relatively cheap (Yuan 2200 equals to USD 362.

Do anyone have any idea about its quality?

Interesting, but not very elegant when compared to the JMI focuser, which has a tiny motor build in. I would expect the rubber band will degrade over time and probably stretch, which is what I would be worried about, particularly if they are anything like the rubber on focus knobs, which perished over time.

Anyway, I use the JMI because of their discrete motors.

The EV 1 cm would be a better focuser, I would expect, but then, it is more expensive.
