Partial failure right off the bat.

After only brief use, the light died.  The tone still works, so it's still usable.

ready for the install. be sure you check on the shaft support they are known to fail within the same time period

Product failed in one section, approximately 12 inches. Worked for a few days then stopped in the one section.

The sensors are accurate and seem reasonably durable, but the display console provided was inoperative right out of the box.

Install is simple, design is universal. However, the part failed three weeks after installation. Bases on other reviews, quality control seems to be rather lax on these components.

Bought this item from seller "eachbid". Unit performed fine at first, but after a month of disuse during which I left it sitting on a windowsill that receives sunlight, I tested it and found it was out of power. I dismantled it and found one of the wires to the solar cell had not been soldered in place. This is an easy fix, but indicates a lack of quality control, and if you don't know your way around a soldering iron you're taking a bit of a risk buying one of these. Unit can be dismantled by prying 4 tiny rubber caps off the bottom, then using a precision phillips head screwdriver. Powered by a three AAA battery pack labeled Ni-MH 3.6V 750mAh. It is also not waterproof; water will pour off the top, but the device will not survive immersion in water and open slots on the underside leave it vulnerable to moisture.

Bought this to replace a pair of worn links on an '03 XJR. Even though I've read other reviews of URO components, I decided to give cheap a chance. Within 6 months, the right side had completely failed again, requiring another replacement. So while they will work in a pinch, and will at least last a little while, I won't be taking a chance on cheaper components in the future, with that sort of uncertainty on longevity.

Replaced and failed in less than a year.
Second replacement lasted a couple of weeks.

I have had about a 50% failure rate. Some complete, some partial failures of light sections. Mostly seems to be poor soldering. Heat seems to affect them.

Fell apart before it could be completely installed.

While using this set in a typical application I actually had a socket break in half.  This is a low cost set, and that is reflected in the quality.

I had to update this to a one star review.  This unit slowly started failing, but could not pinpoint it as such with my voltmeter on the bench.  The issue started as an intermittent slight misfire at idle, between 800-1000 rpm about a month after install, without the engine light coming on.  My car has OBD1, so not super easy to read real time data through the computer, saw nothing strange. Issues ended up getting slowly worse at idle and some while driving and the engine light came on.  This was 4 days ago, so I went through my computer and was getting a random misfire code, so inspected the distributor cap, rotor, and plug wires that were installed new at the same time as this coil in late January (about 2 months ago).  Went so far as to spend $40 at the dealership for the factory plugs, no change.  Next morning the car ran fine, assumed it was a loose connection from the coil to the distributor cap.

Today as I'm driving the car starts and drives decently, as the issue was intermittent and haven't returned in the last 4 days,  then instantly it began misfiring badly on the highway at 65mph and loses power and I begin to decelerate.  I limped it to the shoulder, misfiring so badly it just shuts down on its own, pop the hood, and smell burning electrical and see the coil pack smoking. Saved the old coil in the trunk in a box, popped it back in and it starts!  Ended up grabbing a used OEM coil off a junkyard car that didn't have cracks, purrs like a kitten again!

BUYER BEWARE, this is a cheap unit that may or may not work!

Installation was pretty straightforward. Initial impression was very good, however, one of the three strips started to have trouble turning on after a couple of weeks and completely failed in about 3 months. For the price, 2 out of 3 is not bad, but clearly there are some quality issues. I intend to buy one more pack since I like the light color and performance, but with the expectation that one or more panels may fail.

Fit was okay, but it worked for less than a month.  I had two optical cables in my cabinet, this one an a more expensive one.  This one stopped working, the other is fine.  With a little jiggling, I could get it to go intermittently; now, not at all.  Apparently a crack developed because of the moderate bend I had in it.  Do not buy unless you have a pretty straight shot out the back of your unit.

I own two of these SSD's; the first was bought for my work laptop, and, happy with the performance, a second was bought for my backup server.  After six months of very light usage with minimal writes, however, the second drive has utterly failed, taking my working backups with it.  Considering that I originally bought these SSDs intending to protect important data from the jostling associated with the TSA and my laptop while I travel, I am quite displeased.

Kingston's quality assurance practices on other devices has been suspect, lately, with the MTBF dropping and number of dead out-of-box devices on the rise.  I recommend doing some research with other individuals with SSDNow devices after a few months of use and see if they have comparable problems before entrusting these drives with working data sets.

One of the ports stopped working almost immediately.

Liked it for the most part, but it just stopped working yesterday.
