The left bumper stopped working after a few months, which is ridiculous for a 60 dollar controller, especially since the xbox 360 controller was so well built and microsoft just dropped the ball on this controller.

The bottom of the bumper (where the lightning cable gets plugged in) started breaking shortly after using this bumper.  It's cheaply made, but it gets the job done.  I wouldn't purchase again.

At the three month mark I noticed the white function on one has stopped working although it still functions as only a turn signal. Amazon policy instructed me to contact the seller. I will try to but do not hold out much hope.

It stopped working after a few months, feels like it was built cheap, I wouldn't buy again

Broke after a few months, now it only works if you mess with it and wiggle it around for 5 minutes

worked for a few months in my car, but after a while they started to cut out and had to be moved a certain way to work, I don't ever bend or mess with them so I don't think they should be doing this.

It was fine while it worked. It had some issues with light changing inside the car (as in from sunlight) making it skip a song randomly. This was fixed by putting it in a spot where the sun won't hit it with the downside of not being able to use hand gestures to control music. It died after a couple of months however so I will look for another option.

The sound quality of the mic and earbuds was good, but the left earbud stopped working after 4 months and I cannot find any contact info anywhere for the manufacturer to fulfill the warranty.

Hello

I have received this Bumper, But the power button is not working some times. I asked for a replacement, Need to see what comes up next.
Thanks

After less than 5 months the left side has stopped working. There's no cuts or abrasions in the cable that connects the two ear pieces, but no sound comes out of the left anymore.

Photive shipped me a new pair of headphones that stopped working in under a month. It was the same issue - sound stopped coming out of the left earbud.

I emailed them about this issue, and now they are refusing to honor the warranty.

Worked well for a several months, then the left stick started malfunctioning (only going in one direction now), controller wasn't dropped or other wise roughed up, just started malfunctioning while in use.

The bumper itself is fine and holds up well but the little metal buttons on the sides for volume control and power on/off tend to fall off after a few weeks.

I have had this case for 6 months and was quite happy with it, and the low price was a bonus.  The bumper case fits snugly around the phone and has protected it from a number of drops.  But the plastic pieces which hold the rotating holster clip to the shell broke and there is no way to repair it.  I tried using just the shell as a case, but because I prefer a holster, I'm going to get a new one.  Given the price, I might just get a couple more of these and when one breaks, just throw it away.

The left side stopped working suddenly. I only got two months out of them. The voice announcing battery level every hour is super annoying as well.

But one of these items came broken along the seal and, since I live overseas, I was unable to send it back for a replacement. Fit for purpose. But looking at other similar bumpers that have been fitted for a while, they will need some basic maintenance to keep them looking good.

Great look, and I find the exterior quality fine. Sadly, after only a few months the second hand sticks and the other hands then cannot rotate. A gentle shake temporarily remedied the problem for a few days, but now it doesn't work.

I bought this a few months ago, and it was broken when it came.  It would work for about a second if I jiggled the input for a while and then didn't move a thing (like I had to hold the phone in my hand in exactly the same position).  The second I tried to drive or move it, it stopped working.  None of my other car charged items are like this so its not an issue with the car.
