Worked great until...

I LOVE these headphones, they sound great and are pretty comfortable...but after a month or so they started to crackle occassionally and sometimes even cut out completely. If you unplug it and plug it back in it usually fixes the problem but sometimes you have to do it like 5 times. It's started to get so crackley and choppy i can't even enjoy using them anymore. I have messaged to try and get a replacement but so far nothing...

These headphones worked great right up until they just quit working.  I was easy to sync them to my phone. The range on the Bluetooth was great.  I could leave my phone with my keys in the cubby at the gym and I never lost my signal or had static.  They worked great for a couple of months.  When I took them off the charger this week, they wouldn't turn on. If they had lasted more than three months I would have given them 5 stars.

Worked great...for 5 months. Now it won't turn on or charge, and 3M is unresponsive. Very disappointing. From the other reviews, which I should have read prior to purchasing, I can see I am not the only one with this issue. I decided to replace it with a projector from a different brand.

Worked great.... for 6 months. Now every 3-4 days the outside reading goes blank and I have to retrieve the unit to reset it. New batteries didn't fix it. Will be buying a different brand.

The thing worked great and was perfect, I used it in my car, in my garage so I could keep my phone with me instead if plugged into the sound system.  Even used it with my projector to output the sound to my Bluetooth sound bar and it worked great no noticeable lag on the voice with the video.  However, about two months ago it stopped working. I traced the problem to the 3.5mm jack when you move it around it works but any movement and the sound goes off again, its not usable anymore. Not sure if they are all having the same problem or I just got a defective one...

Worked great until warranty was over, then died completely.  Have read reviews in other forums and several have said the same thing.  Going to try to talk to customer service- see what happens.

This thing worked wonderfully for a few months, but then all of a sudden it just stopped cutting through the rim-- it just cut a groove.  Even if I let it go around multiple times, it would never get through.  Bummer, because while it worked it was great.

Product worked great while it lasted, but just stopped working.  Others have had the same problem, but I never thought it would happen to me.  Literally worked one night and the next day - nothing.

Before it died, I spent the time to clean it every week.  I guess our water has a lots of "stuff" in it because the cleaning process was a real pain and there was the hard white mineral residue on the plastic and the grey hub (I'm guessing the heating element).  Although it was time consuming, I didn't mind doing it because in my mind, that was stuff that I could have been breathing in.

So while I would have given this product a 4-star rating (minus 1-star for the many parts that needed to be cleaned and the difficulty in doing this), I can't say that I am at all happy that the humidifier lasted less than a year, especially for this price.  This gets 1-star.

Worked great out of the box, but after only four months it stopped working completely.

When you have a laptop with only 2 USB ports, but you're a photographer who sometimes works with 3 or 4 external drives, this kind of device is kind of necessary. I've trusted Anker products in the past, so felt confident buying this...and it worked great.

But only for about 6 months.

Now, nothing I plug into it will be recognized by my computer. Not external drives, not phones, not USB sticks....nothing. The drives / devices are getting power through the device, as they should, but the adapter is just not communicating data to the computer. To make sure this wasn't a problem with my laptop, I also connected it to my desktop machine... and the same issue.

Long story short, within 6 months, this became nothing but a useless piece of plastic.

Worked really well for a few months, then suddenly stopped

Worked wonderfully up to today, when it suddenly stopped working with no warning. No breaks, bends, or any sign of damage to the charger - it just stopped working. It broke just under a year from purchase and should have a 3-yr warranty, but there's no way to contact the seller for a replacement.

Worked great till the second time I used it and it stopped working.

Worked great for about six months, then the regular HDMI side fell off when I was unplugging the cable from my monitor.  My wife used this to watch shows on her Kindle, on a second monitor, when we were away from the TV in the living room.  Also used it in hotels to watch Netflix.  Until it broke.

Worked great for a few months. Recent development is that it stopped working and I need to figure out why.

These are great - until they quit working.  After only a few months of very light use, I can no longer access the drive.  It makes a nice paperweight, but it's useless as a backup source.  I won't buy another of these.
