I have been using this filtration system for a week-long backpacking trip in Honduras every year for the past 10 years (the same bags, they have held up really well!). We filter around 12 liters of water at least 3 times a day for between 7 and 10 people. The water in rural Honduras is very dirty, but this filter works wonderfully. We "backflush" the filter cartridges every time we use them (leave a few ounces in the clean bag and reverse feed the water back into the dirty bag; it removes sed...iment from the cartridges so they last longer). I am thoroughly impressed with this system and would recommend it to anyone!
This is the first gravity filter system I've owned. I owned pump filters in the past. This purchase was long overdue as it is a tremendous time saver. I've used other people's gravity filters such as Katadyn. I chose this system over Katadyn because of the in line filter. I could use it to suck water out of cracks in rocks if needed which helps bridge the gap in functionality between pump and gravity filters. The only downsides I see to the inline filter over the in bag filter like Katadyn is... that it is easier to clean and visually inspect for contamination/clogging with the Katadyn filters. This being an enclosed filter, it is harder to dry out. I often camp in below freezing conditions which can destroy a filter if water freezes in the filter. If and when this happens, I would get a Katadyn filter for winter camping and use the GravityWorks filter the rest of the time. I use alum powder for silty water and it keeps the filter running smoothly.

Does this include the black storage case that I see on other websites?

Yes, it comes with a carrying satchel (small black bag). This filter rocks, I have owned several other types and use filters a lot backpacking. I was really surprised at how fast it is too. Keeping the filter fresh is key to the speed.

Yup. Has a black mesh carrying case. Just used it on a hike over the weekend. Worked better than expected. Connected the unit to the bottle adapter (sold separately) and directly filtered stream water into a Nalgene 32 oz and a Platy bottle 2L.
