I have a Celestron 130 slt and although it is a Newtonian not a mak-cass' it gives stunning views of Jupiter, Saturn, the Moon and even the Sun (with a proper solar filter of course!). All of the SLT series share the same instruction manual so I assume that the set up will be the same. My 130 slt can fit in my backpack offering good portability and sets up in minutes.
The mounts computer/handset has given me only one problem (it gave me an error and I couldn't use the telescope until the connector cable arrived from America) but other than that it always got the alignment spot on and is really easy to use. I also believe that all the SLT mounts come with AA battery holders built in them (mine does) which is very handy. Although the batteries in mine last about 2-3 nights (but it uses 8 AA's at a time), I still invested in a Celstron Power Tank - complete with lights, radio and car jump starter.
The only problem I have had with the tripod is the fact that it is very light and can shake which gets really annoying. A few bags of rice on the accessory tray helped solve this problem.
The red dot sight I found extremely helpful down south away from light pollution as it offered a simplified view of the sky - great for beginners, but back home in light polluted skies the red dot sight could only show you what your eye can see, which is very little. At home though you can buy a dovetail finderscope which you can replace the red dot with. Also if the seeing conditions are at least mag 1, you can pick 3 bright stars and the computer will automatically align itself and you can pick any of the objects in the mounts database, meaning you don't need the finderscope after alignment.
I have had no problems with the focus mechanism and will even go so far to say that it is relatively smooth (as long as you loosen the screw, which I only recently figured out
)
The only other problem I have ever had with my 130 is collimation. Celestron has implemented a pretty helpful collimation system which uses no tools but the instruction manual still shows the tool system so I had to research for quite a while to see which knob does what (just so you know the thinner one is the locking screw).
This reply is based on my experiences with my
130 SLT which uses the same mount/tripod, computer/hand controller, focus system, red dot sight and dovetail mounting system. I can not speak for the sky watcher telescope but I can say that Celestron make quality telescopes and the SLT models are great for beginners and offer great views of solar system and DSO's.
