I got a set of these in red a few days ago and after installing them here is what I think about them.
My very first review so be kind but constructive.
They come in two lengths, 1 meter (around 10.00 US) and 2 meter (around 15.00 US) lengths and they are pre-sleeved from the manufacturer. The sleeving is of good quality, similar to Techflex, and only offered in black.
The LED bulbs are 3mm's in diameter. There were no specifications on the brightness of the LED's or their power consumption. Being LED's, it's most likely negligible but knowing this information could be of use to us watt misers. I'm sure with a call to NZXT you could get this information. The kits are offered in a variety of 5 same color per string of LED's; Red, Orange, Blue, White and Green.
The PCI, IO control has a 3 light level intensity 3 position slider switch and an on/off button. There are no overly bright colors on the circuitry parts on the PCB to break the stealth design.
During my install I discovered the power lead coming off the PCB stuck out because the power lead is mounted at the end of the PCB instead of next to the PCI cover plate that it's mounted on. I'll have to think how I will correct this problem because it looks out of place just suspended out in mid air the way it is.
I also discovered that you had to have the areas where the mounting clips were going to be located cleaned very well and that you had to press very hard to get them to stay. I removed their adhesive and used 3M's 4010 heavy duty tape to make sure they didn't fall off anymore. I hope they switch to a stronger adhesive in the future
At the end of my routing I had about 9 inches left over so I had to loop it back and black zip tie it to the routed strand. It's not a problem except for the extra bulbs in one area. It makes it noticeably brighter in that one area. It would be nice in the future if they make the bulbs socket-ed in some way so you could just remove the offending bulbs.
I also noticed that the ends of the LED strings are terminated. It would be useful if they made them so you could interconnect them or daisy chain them somehow. Making all their strands 1 meter and connectible would offer some adaptability.
My kit included the following;
1, 2 meter pre-sleeved red LED string of lights.
14 Black mounting small mounting brackets with double sided adhesive (there weren't enough mounting brackets for my installation and I spaced them out).
1 all black pre-sleeved molex adapter.
1 black PCB mounted to an also black PCI cover plate (does not mount in Mobo's PCI's) with 3 position light intensity switch and an on/off button.
Results
Very nicely done, but still room for improvement. Professional, stealthy looking product and solidly built. The wiring, bulbs and mounting brackets are small enough you can hide it almost any where. I didn't even find any fraying at the ends or where the bulbs poke thru, or for that matter any where on the sleeving. I'll buy one again.
PRO'S
Bang for your buck
Excellent quality
Built in 3 stage light intensity control and on/off button
Stealth all black
CON'S
Weak adhesive for mounting brackets
Fixed bulbs
Non interconnect-able
Power output connection/lead needs to be re located next to PCI cover plate
Endless uses
