Initially these worked great.  However, the edges are "tapered" or thinner - which after the first or second use flips up and won't sit flush with your skin.  If you're wearing tight fabrics that is fine.  However, if it is blousy or your clothes brush against them at all then it catches on them and you can see the edges roll up.

They were great at first, but then after 2 days of barely using them, the charge port shifted and moved without any reason.  They were good at noise cancellation, good range, easy to connect to blutooth, good sound.  I knew they were too good to last though.

I purchased these cables and they worked really well at first. No complaints. But the first two have gone downhill the same way. I'm on my second and they both started to charge slower and slower. In fact, they just makes the battery drain slower, not actually charge it. So I guess I have one more and then I'm out of luck.
Edit: I contacted the company and asked them for a replacement. They were quick to respond and I didn't have to wait too long to get them. I still think the product is somewhat dysfunctional but these work better.

They started out alright. But after a few months they just kept disconnecting. They no longer work. Probably won't buy the same model for replacement.

We own four of these.  Initially (likely within the time frame most of the other reviews have been written) they work GREAT!  They are light, durable and quite handy.  But over a period of months the very fine mesh screen starts to clog up. and no water passes through.  Essentially, they TOTALLY stop working.  We have tried everything short of acid to clean them -- hot water, soap, alcohol, toothbrush, etc.  Shortly after I write this I will be dropping all four of them into the trashcan as I look for replacements.

These start out great. But after a few months they seem to get loose in the micro USB end and stopped working in my old S4. They appear to be cheaper copies of the Paracables.

I bought the 5 pack of 10ft cables.  Initially I loved the cables.  Gave great range sitting on the couch and not having to worry about pulling the cord to tight / causing a kink.  After a couple months the micro end of the cable did not hold in place any longer (seems like the little nubs wore down).  I didn't use them all at once, as one wore out I tried the next cable, etc.  At the end of the day 4 of the 5 cables ran into the same problem with the nubs - the 5th cable was a casualty of my teenager - though statistically after 4 of 5 had nub wearing issues, I assume the 5th would have also.  Strength of the cable seemed great.  If not for the nub problem I would have recommended these cables, but since they did not last long I would not be able to recommend them.

These worked great for a month.  After that, they would not charge for very long and the magnetic holders would not keep the plugs in place.

Bought 2 pair and within just a few months the seems came unravelled.  They worked great otherwise.  Wore them to work and they really reduced my fatigue by quite a bit. Unfortunately, they're useless now.

For those who like the idea of the reflective patterns, that started wearing off within a matter of weeks.

BTW, I never once put them in the drier.

Bought a 10 pack of these and they worked great initially.  About half have died within a year across 3 different light fixtures. Sadly, that's not the worst of it... when removing the bulbs (which really I shouldn't have to do since LED's supposedly last decades), the "head" bulb area comes undone from the base of the bulb, effectively coming apart. This necessitates me getting pliers to remove the remaining "base" from the fixture.

I've had no other problems with the various LEDs I've bought for various fixtures in my house, so I don't think there's some electrical problem within my house... and as noted, since this is across 3 different light fixtures, the problem can't be blamed on my fixtures.

These worked great. They fit into my Asus 2012 Nexus 7 tablet without falling out. Also work great for daughter's HP Windows tablet

UPDATE: I used these cables one at a time. Each one in turn became useless within a few weeks and would not stay plugged into the device I was using. We own several cell phones and tablets in our family and the cables just fall out of the charging port. I am back to square one looking for quality replacement chargers for my family's devices.

They worked great at first, but with frequent use, the connector for the phone end starts to get loose. It still rapid charges, but it falls out from its own weight. Doesn't stand the test of time in that regard.

These worked great for approximately 8 weeks.  I use them for transcribing.  Right the middle of transcribing, they completely stopped working.  I tried unpairing and repairing, restarting my computer, turned them off and on again several times, made sure they had a full charge, etc.  Amazon said it had been too long to be able to return them.  Wrote seller and explained the situation, and didn't get back to me.  Unfortunately I have to say buyer beware.  They don't seem to be very good quality.

I would initially give these a 4.5 star rating.  I purchased 6 strands of them last year in October 9th, 2015.  I mounted 5 of them to the eves of my house with clips, and I made sure to waterproof the connections to avoid corrosion.  They looked great for the first 4-5 months when I was using them.  The holiday season ended so I unplugged them and turned them off. Skip forward to now, and the problems showed up.  I plugged them in to see if they still worked, but they did not.  I had a few of the LED's in the middle of the strand that would not change colors.  Some would stick on blue while the others were red (or some other color).  This wasn't a huge deal, but it is definitely noticeable when.  I also had one strand that went out completely.  I thought it might be the connections so I checked from both sided of the strand to see if I could get part of the stand to work, but had no such luck.  I did have luck in that I purchased an extra strand to replace the completely dead one.  I contacted Supernight Direct to see if they were covered under a year warranty.  They replied my warranty time expired hence my now 2 star review.  LED's should last more than 1 year, but these did not.  I little disappointing.

Worked great for a few months after installation and then at least one of them quit.  Replaced them with a different brand.

These headphones worked great and sounded fantastic when I first used them. However, after a few months of use (just 1-2 hours a day at the gym) they have started cutting out. I keep my phone in my right pocket of my shorts and whenever I turn my head to the left they cut out. It has been getting increasingly worse since I started noticing it and it has gotten so bad that I can't use them at times.

I gave this 3 stars solely because of how they worked originally.

This were great in the beginning, but after a short amount of use, each one started to look messy and uneven. It's a shame I wanted to love these :(
