Long review for the OP:
I have used mine for quite some time now. They truly live up to their name "Super Light"... Carrying it around by hand or on my back is effortless, which is the biggest plus of this case. This will be lighter than other polyfoam cases on the market and certainly lighter than any hardshell case. Having a case this light really makes handling it a breeze. I often transport my guitar to different venues and such so this matters a lot to me. I have a friend who has a Hoffee case and I personally can't imagine lugging that tank around. I used to use a Visesnut case which is very light, but this Super Light is significantly lighter. It also has a nylon exterior so accidently bumping into walls and such isn't an issue.
Personally I feel that guitars can better survive a drop in a polyfoam case than a hardshell case because foam absorbs and distributes the shock rather than transferring the shock to the instrument. My guitar has accidently fallen over in this case pretty hard with no damage. Another member on this forum had the headstock on his guitar break just from a light drop in his hardshell case.
Why $200? It is probably more expensive because of little details such as an outer shell that repells/beads water, it has a water resistant zipper, it has a lockable flap using a key that keeps the guitar closed even if the zipper is open, it has metal hinges that keep the top and bottom pieces together, it has some velvet lining inside with some light padding, high quality back straps and hardware, metal feet so it can stand on its own, an inner compartment that opens and closes on its own, better styling, smaller footprint, etc.... You'll notice these little details that other polyfoam cases do not have. $200 indeed is a bit pricey and probably overly so, but it depends on if the case meets your personal needs or not.
The large spacious pocket on the front is a huge plus... I put my Barnett support, Barnett armrest, books, bartlett mic, microphone chord, etc. in there. It fits a tonne of stuff. When I used to use a visesnut case, it had like almost zero room for storage so I'd have to carry these things separately. With the superlight case, I can fit everything I need and the case will still feel light and manageable when fully packed. This is one reason I probably can't go back to other cases that don't have these storage options.
Another plus is the company stands behind their product. I had a minor issue with one of the hinges, and the company sent me a brand new case free of charge, hassle free.
For an around town kind of case, it is convenient and will provide ample protection. The major draw back of polyfoam cases is that it has limited crush strength, so you can't stand on top of the case as you could some other hardshell cases... otherwise I think it is superior for shock absorption. As James Frieson has experienced, you can ship a guitar in it without any issues.
With that said it isn't perfect. I would prefer that the polyfoam were thicker and more rigid in some parts as it is on the Gator or TKL polyfoam cases, but they probably shaved it down to make the case the lightest case on the market. The fit of the guitar also isn't perfect... I think they made the inner compartment a bit larger so that it can accommodate larger sized classical guitars. So what I do is put a piece of foam at the top of the headstock to ensure the guitar does not move around while in transit.
All in all I'm pretty happy with it, but it may not be for everyone. The only other polyfoam alternative that is readily available is the Gator Lightweight Polyfoam case. I opted not to get this one because the handle design will break after some years of use if you use the handle often, and the backpack straps attach too high on the case, so the guitar will ride too low and bump into your legs if being used as a backpack. The gator also has less storage space in the front pocket.
