Beware, did not work for me (edited, see below)

I pre-ordered and received yesterday. I anxiously tried it out, hoping to be able to stand closer to the kinect. Alas, looks like the product is fundamentally flawed. The Infrared picture is totally dark start with, and the kinect tries to increase the contrast. Was able to see me OK, but the hand tracking was EXTREMELY erratic to the point of being UNUSABLE. Painfully went through the Calibration process a few times. Sometimes, the Kinect would complain that it could not see the floor. Sometimes, it could see it OK, and calibrated fine using the card. However, when I try to play any game, just getting it started is a chore, since the hand movements are barely successfully tracked. I thought this was because the room was not too well lit (I have two lamps in front, none in the back), so I tried it again this morning. Same results. Calibrated OK, but could not even get a game going. Looks like the IR light is severely attenuated by the lens, so the kinect can only barely see me in IR. I will be trying some more tests when I get back home tonight, but so far, the verdict is that this is a total NO GO for me. If it is like this again tonight, I will be returning the unit to Amazon.

UPDATE AFTER FURTHER EXPERIMENTATION:

I think I figured out why the reviews are so bipolar. I have my Kinect mounted ABOVE the TV, because that is what works best in a limited space. However, the Zoom seems to work best when the sensor is BELOW the TV. I unmounted mine and placed it below, and went through the whole calibration routine again. Now, I was actually able play some GAMES! How about that. Played with Kinect Sports (Soccer, Ping Pong), Kinect Adventure (Reflex Ridge) and some Dance Central (just the basic Poker Face). It all played OK, with me standing about 3-4 feet from the sensor. HERE is an additional catch: when the sensor shows if you are in the "good" or "best" position in the game, try to stand back as far as the room allows so it thinks you are farther behind. Then, when the game starts go ahead and move up front. It seems to work best this way. Perhaps the initial distance determination is by some kind of an ultrasound range finder, and that can't be fooled by a lens, but the subsequent computations are based upon the IR field, which IS influenced by the lens. Also, the IR reflection is stronger the closer you are to the device, so it works better.

Anyway, I am revising my stars to 2 because I could actually enjoy some game play with this thing. However, Nikko should have warned about the fact that this ONLY works for sensors mounted below the TV,  and that too only in a limited fashion. I still have trouble getting it to recognize a hand wave even in the lower position. Takes me a while, but once it does, it seems to go better from that point. ALL REVIEWERS: Please state where your Kinect is mounted along with your review, thanks!

FINAL UPDATE:

I tried various games last night. Even in the lower position, hand tracking is very erratic. On some games it is totally unacceptable. For example, in Child of Eden, the hand tracking is critically important, and with this thing, you keep shooting at the wrong time, totally spoiling the fun of the game. At this point, I have given it the largest measure of the "benefit of doubt" and am giving up. I just filed for an RMA. Oh well, it was such a nice idea. I believe the only way this will work is if MS creates a supported update firmware that recomputes the geometry based on this new optics, or comes out with a version of their own (Kinect 2?).

The product simply did not work, and I am returning it. Quite disappointing.

When I received the product, I plugged the hub into my laptop, where the hub was correctly recognized. The blue light on the hub also came on, as expected. However, any device (tried mouse, keyboard, external harddrive and a flashdrive) plugged into this product would illicit an error message saying "Unknown Device" and would not work. These are devices that work perfectly when directly plugged into the laptop. For reference, I'm running Windows 7.

I tried some online tutorials to address this error message, but nothing worked, so I am returning the product.

Read all the great reviews, but what can I say...it doesn't work for me.  Bought two of these for my laptop.  Followed the directions and immediately got a blue screen after plugging in the USB's.  I'm an engineer and tech literate, running a souped-up Dell laptop with the latest Windows 7.  I wish I could give it 5 stars, but it has to work first...

update...and so 10 minutes after posting this review, I tried plugging in the monitors without uninstalling the software, and lo and behold it worked.

Sounded like a winning scenario to me.  Unfortunately, this device was DOA - and with the amount of trouble it takes to pack this up and send it back, I don't think I'll be taking another swing at this.  I'll try a recommended one instead.

REVISION:

Like others with issues with this product, I was contacted by the seller to make good on the product in exchange for revising my review.  I agree to re-evaluate the product; they drop shipped me one completely free of charge (note: this was after my Amazon refund had cleared) in hopes of making good on the product.

I agreed;  I liked the case overall - I appreciate the ease of being able to swap drives in and out.

The new one arrived and it worked as expected.

Would I NOW recommend this product?  I changed my review from 1 star to 4; namely a star lost for the issues I experienced with the first unit. There is obviously a production line issue somewhere along the way and the seller need to address this issue.

If you do decided to pick this up (it's a neat case), don't bother returning it to Amazon.  Contact the seller as they appear to be ready and willing to make good on their product.

Didn't do the job advertise ( had to put 1 star, but actually wanted to put 0 stars)

Did not work.  I returned.  I should have read other reviews before purchase.

I was ready to write an absolutely scathing review of this product at first...BUT I have since changed my mind.

I purchased a new laptop several weeks ago and like an idiot did not realize that the new laptop did not come with an internal disc reader. major boo. I also did not realize that the new laptop was not compatible with my existing printer, it required a wireless enabled printer. another boo. So I knew i needed a disc reader so I started researching and came across this model. For the price and claimed ability, I figured it would work well for my needs and purchased it.

It arrived in a timely manner and I was eager to install it and start using it...that's where the trouble began. I am a fan of following instructions since ultimately it saves time and prevents you from fuc*ing things up and having to go back and read the instructions anyway. I made a smart preemptive move and bought the USB Y cable for external devices just in case I needed the extra power (highly recommend this, especially since I only paid $1.99 for the cable). I plugged the drive in and inserted the installation software and waited...and waited...and waited. My computer recognized the device and was attempting to install the software but was getting stuck in the death loop that everyone else with a windows 8.1 OS has mentioned. I attempted the installation for over 2 hours with continuous failed results. by this time I was PISSED. I had tried to search for a driver for the device online on EVERY site and self-help forum I could find with NO luck. I was ready to pack the piece of crap back up and return it to the seller first thing monday morning. I, being righteously upset, decided to post a rant on facebook that one of my friends saw. She has a sister who is an IT geek (said in a loving manner) who wanted to see if she could take a look at it and try to help.

Long story short, if you are stuck in the installation death loop, try plugging the USB cable into each different port on your computer and trying it again. Also, try alternating on each port with the USB cable provided with the product and with the USB Y cable that I HIGHLY recommend getting. I was able to get my device installed on the second try with switching ports. Fair warning, when it DOES eventually install, there are some extra programs available that take some time to load and in my opinion for what i need this product for are useless to me but will undoubtedly be useful for someone else. DONT GIVE UP!!! This product will install eventually.

Didn't work for me.  Could not get any of the adapters to transmit ANY signal.  DOA.  NOTE:  If you appreciated this review please give it a thumbs up/like your helping me to continue to give honest/unbiased insight into products Ive used and you may have questions about.  Interested in a product but don't know enough about it and would like it reviewed?  Please let me know and I'll see what I can do... Thank you

another return.  Did in fact not work with my older setup, despite being advised that it would.

Didn't work no matter what I tried, even modifications to the card itself.

Could not get it to work.  Went with the expensive adapter and an extension cable

I was never able to use the cable for it's intended purpose as when plugged into my 2.5" SSD drive, my computer refused to recognize it being a valid drive.  I had to end up plugging the SSD  directly to the motherboard to clone my hard disk, which defeated the purpose of having this cable and cloning it before hooking it up to the computer.  It also would have been helpful to include some sort of directions of how to use the cable, as it was unclear at first that BOTH usb connectors need to be connected at the same time.  Having never used one of these before, I was unaware of this.  Not sure if I simply received a defective unit or not, but this was a waste of money for me. Luckily it was not very expensive or I would be seeking my money back.

Update - The seller has contacted me and issued me a full refund at my request.  Due to this refund I am now updating my review to reflect a more favorable rating.

DID NOT WORK!! Glad to see other postings about it not working too (though feel bad for you all)...it's validating as I wondered what happened, esp after a pet store recommended Advantage.  I'm switching brands.

When I first tried this cable, it did not work. All I got was a loud interference name and no picture. Then, a few days later, I got a strange idea. "What if the colors were swapped?" Low, and behold, this was it! The only way I could get the cable to work was to plug the white cable into where the yellow was supposed to go, and vice versa. To clarify, it seems that somehow in the manufacturing of this cable, the wrong colors were put on the connectors. Normally, the yellow output is for video, and the red and white were left and right audio channels. For some reason, the video is actually going through the white connector. For me, I connected red to red, yellow to white, and white to yellow. Perhaps, they had a color blind worker in the assembly line... I dunno. However, the cable does work when used this way. I will plan to put yellow and white tape on the connector ends to correct this problem.

Correction- I think that RCA and other brands use a different wiring scheme. For me, the cable did not work correctly until I connected it with different colors than normal (see above). As mentioned by another person, this may not be a flaw, but a difference due to RCA's wiring scheme. I have added a couple stars to the review since then.
