Product review (3 stars): Good Looking Range Hood with some Warts
I just installed this unit and it looks great, but has some warts.  First, the commercial grade stainless used is definitely not 304 stainless (18% chromium/8% nickel) as it is very magnetic. There is nothing in the description indicating the composition of the stainless, but it certainly has no or very little nickel content which does reduce its ability to resist rust.  No idea how it will handle a humid environment going forward, but it is a concern.
The internal electric interconnect housing has a top and back "knockout" which must be drilled out (it is not truly a knockout).  I drilled multiple holes to remove the bulk of it and then a dremel with a grinder attachment to open the hole up as required for the romex connector.  This was much more effort then necessary.  The unit comes with the wiring out the rear which is fine for initial pre-installation checkout.  To utilize the internal interconnect box, as most electrical codes would require, you must remove the plastic cable cord closeout from the rear surface and pull the wire back through the internal interconnect box and cut/trim to suit. This was no big deal but there was nothing in the instruction manual noted. I routed the house romex through the top which interfered with the top right 4 inch wide attachment board the instructions called for during initial prep.  This board had to be removed and cut for the needed clearance for the romex cable connector.  This is no big deal but something the instructions could have indicated.  Access to the internal connection box is very tight, but no issue if you do all the electrical work before mounting the unit. Believe me, it would not be fun to wire this unit after mounting.
My wife commented immediately after the installation that the lighting of the rear burners was not very good and asked why the lights were not angled slightly to the rear, (or possibly additional lights placed on the rear) as opposed to straight down.  I don't believe this to be a significant issue, but I am not the cook.  I do take issue with the baffle filters. These filters have two tongs on the rear and a spring loaded sliding tong on the front that fit into mating slots.  They do not feel secure and one actually fell out while cleaning the outside of the unit.  I found a screw adjustment after this mishap (no mention of this in the manual) for the spring tension on the front tong which does not improve this situation.  It appears that the rear tongs are too short and the fit of the baffle is to sloppy to ensure the baffle will not fall onto the range.
The fan has 6 speeds, 0-5.  When you power up the fan it comes up in fan setting 3 and you increase or decrease the fan speed from there.  At the lowest setting which is called "Quiet Mode", there is no question from the sound level that the fan on. In my opinion, "Quiet Mode" is not very quiet and would never be mistaken for the fan being off.  I still find the noise level to be acceptable but I used to play in a rock band.. your mileage may be different.
Follow up- I contacted Kobe Service concerning the filter fitment.  They gave me the Kobe engineering number in California.  I talked to Monica who asked that I email the details which were needed for documentation before shipping out replacement filters.  They promised to check the filters dimenionally prior to shipping out and try to determine root cause. They have been very responsive. Will update as this plays out.
-- I just received replacement baffle filters and the fitment is no different than with the originals, which were shipped back to Kobe earlier this week. Have emailed Kobe service and awaiting reply.--In the meantime, I found a solution to the filter fitment issue.  The filter rear tangs fit into a verticle thin bent metal channel. I pulled this thin metal slightly forward (it is springy) and placed small wooden blocks in the channel which forced the slots at the top of the channel slightly forward. This closed the frame to filter gap sufficiently to secure the filter. Maybe not the most elegant solution, but it works.
---Update- Kobe emailed and are having baffle filters made with longer rear tangs to address the issue.  Looking forward to new filters being sent that eliminate the root cause of the issue.  This will take an estimated 6-8 weeks.  Thank you Kobe for taking appropriate action to correct this deficiency.
--I received a further email from Kobe months (7/11/2014) ago that the real problem was improper tolerancing of the baffle opening.  I did not receive new baffles with longer tongs as previously promised and have not received any follow-up to correct my issue.  I have no idea if the units manufactured now have been corrected. They stated "The newest set of filters we received are still the same as last. We have been going back and forth with our design department to see what exactly is at fault. Recent events have shed light on the same problem you are having. We have concluded that the problem is not within the baffle filters, but instead within the hood itself. Although increasing the length of the rear tangs will fix the problem, it still does not fix the oversized gap. We are currently in the process of fixing this in terms of quality control. It is highly likely that the warranty department will approve a replacement since the opening for the baffle filters on your unit is bigger than designed. Please give KOBE a few days to confirm".
