5-Pack did not last as long as one very good cable
351408
I purchased this 5-Pack of USB cables in April of 2015 with the intention to share with the family.  They appeared to be sturdy with well made connectors.  However, instead of sharing, I have used each one of them as a replacement for the prior one that stops working after 2 to 3 months of casual use.  I am now on my last cable and it showing signs of going bad as it only charges if you hold it in just the right position.  My assumption is the the wires used internally are small and brittle and after a couple months of being slightly bent they break and the connection becomes intermittent.  The intermittent connection is happening just past the micro USB connector end of the cable.  I have gone through all 5 at this point and will not be purchasing these again.  I think I will purchase one very good one for about the same price.

I bought these for my 8 year old son.  His last cable only lasted 7 months.  I know when I bought these that they were on the cheaper end of the spectrum but I figured since it was a 3-pack and they each lasted at least 3 months i would be ahead in the game.  I guess I was wrong.  When they came they were in a nice zip-loc pouch which was great for keeping the other two cables until they were needed.  The first cable lasted exactly 1-week.  The 2nd cable didn't last the weekend.  So I'm on a week and a half and I'm done to one cable and now have to look for a replacement.  Both cables are breaking at the neck of the 30-pin connector.  The white outer sheath is pulling out of the connector and then the internal wires are snapping.  I get that my son is probably a little rough with them but I expected more of a lifespan than this.  I will not be buying these again.

I have 2 sets of Sol republic headphones for my kids.
each of them have had the cables wear out from use in under a year.
while it is good that I can just replace the $20 cable and not have to buy another set of headphones.
It would be nice if they cables lasted longer than a year

Anker has always been a brand I trusted for anything related to external batteries, including any of the accessories... however with this I'm not sure about their cables anymore. The premium red cables are pretty nice and rugged, however the black cables don't seem to hold up well in rugged conditions or heavy use. Also, I'm not sure if it's entirely Anker or Amazon to blame on the packaging because I received five cables total and of the five, four of them were from Anker. The other one was a Logitech cable with an Anker velcro!

I bought a set of these Anker 6 foot charging cables in June, 2017. At first,  they worked beautifully and I was thrilled with how speedy they were when charging my cell phone. But after awhile,  one of the cables became difficult to connect to the appliances. The end that is supposed to connect to the phone has become too difficult to use. I cannot push it in.  So now, it has been less than five months since I ordered these cables, and I only have one cable left that I can use from this order.
Right after I ordered these cables, I also ordered another of the same type of cable but in the 10 foot length. This cable and the remaining 6 foot cable are still working but I am now wondering how long before they malfunction. In the past, I always trusted Anker whenever I needed accessories for my cell phone.  But after this,  I will have to rethink ordering these more expensive accessories.

It lasted less than 5 months, so that kind of sucks.  Monoprice cables are half as much and last just as long or longer.

You know, you get 10 for the price of 1 name brand cable so don't expect that they are of first-rate bullet proof quality.  I have found that of my 10;
2 didn't work out of the box and were replaced by the vendor for free and nearly immediately. (GREAT customer service!)
1 failed after a few hours of use because the cable pulled out of the head molding.  I try my best to pull the plug and not the cable but i don't always pay attention, so perhaps I'm less adept than some.
1 failed for unknown reasons
This over the 6 weeks I've had the cables.  The remaining 8 appear to be fine and I've experienced no further issues to date.

They are a little less supple/flexible than many cables and generally a bit lower quality, but again, you just got 10 for 1!!!

These cables looked really good quality. After little a month, one of them suddenly smoked by one end of the cable. Luckily, I found out the right time and disconnected it. I contacted with manufacture and was replaced with new one. Again a couple day ago, my other cable was torn of at the end connector to the device. I'm really not sure that I got these defect products or the quality was not last long enough.

worked good at first, loved the longer length, but didn't take long before they stopped working

Worked ok when it worked.  Did not charge as quickly as the 3 ft. cables, but the extra length of the cable was nice when needed.  It also shorted out as did all of my Anker USB cables except the black ones.  Who knows why? Coincidence is possible. I bought several and had the same outcomes with all.  The 3 ft black ones are still going strong. all red ones (3 ft and 6 ft) died.

Each of these cords lasted approximately 10 days. I have had the 5-pack  for 48 days and the last one has become useless.

Each one didn't last a week, I've replaced these with anker powerline plus cables which have not failed me yet.

The cable is fine, but I received one. It said pack of 5. I didn't really care because the cost was low even for one, but it should state that you get one cable.

All cables worked for both charging and syncing. Only used a couple to begin with. One started coming apart after about 5 months of regular use by a teenager; the connector edge started pulling out from the housing. Now have a couple more in service. Really, for $2 each that's as much as I expected. A reasonable value as long as you don't mind replacing them now and then.

They seem to be sturdy cables but one I'm using has already started to fray after less than a month. I'm not really concerned since they were fairly cheap but they get the job done.

Purchased a set in May 2014 and was pleased up until this past month.  Two of the three cables stopped charging my children's iPad 2s.  We made the purchase based on reviews and great service by the Friendly Swede from past purchases.  I know things don't last forever, but I expected at least a year's worth of use out of the cables.  I don't blame the seller, just the product.  Our use and frequency was daily, so consider what you need the cables for before making a purchase.

I order these cables all the time for my macbook. While they work and get the job done they don't last long. The last one lasted 6 months and the 2 before that lasted around a year. I can't complain too much though because I had similar issues with the cables apple supplied when I still had applecare.

I do try to extend their life somewhat by adding electrical tape to areas on the aluminum case where the cable comes in contact with the case. With the last cable that only lasted 6 months I did not add any tape in order to see if the tape actually helped. Perhaps that is why it failed so soon. Not entirely sure though.  2 more cables are on the way and I am going to try adding tape again but this time I am going to wrap the cable entirely with electrical tape. I do feel that the tape does help somewhat especially if you carry your computer around a lot in a bag or backpack.

Picture just shows the dreaded symbol I see on my macbook when the cable goes south.
