changed twice, both stopped working within two weeks

I bought the first one and the light broke on the second use. I thought it might be an exception so I get an exchange. This new one also lasted only two weeks. Don't know what happened. If this happens with a lot of people, then don't waster your money buying it.

One of them broke after 2 weeks and the other stopped working after a month. Not worth the money

2 out of 2 didn't work - don't bother to buy this!

I was super excited when I got this and was very impressed at first. It is a decent case, extended the battery life without adding too much bulk. That was then, this is now the micro usb port to charge has faulty contacts after only two weeks. i have used multiple different micro usb cables, tried cleaning the contacts etc. it only charges if i hold pressure at an angle just right to put just the right amount of force on the cable. Totally bummed. I don't usually write reviews, but having thrown the package away two weeks ago i am stuck with an expensive piece of junk that doesn't work and wanted to save others from a similar fate.

Picked these based on the reviews and was disappointed to find that they both stopped working after a few days.

These are very nice cords; good looking and appear to be durable.

However, one of the three cords I bought stopped working after two weeks. There is no apparent damage of any kind. Boom, just stopped working.
It makes me wonder about the other two.

September 23, 2016 update: The second cable I plugged in quit working within 24 hours. I am returning the lot. DON'T BUY THESE!

The unit stopped working after less than two weeks of use. In touch with AOC to get a replacement.

spent good money on two of these and both stopped working within 2 weeks of purchase. What a horrible waste of money.

Two outside units stopped working after approximately two weeks even after replacing with new batteries. Two other units are fine.

I've had two and they both have stopped charging, requiring lots of wiggling

Both units began behaving erratically within 60 days; randomly switching to bright (calm night, nothing moving) to such an extent that the batteries were dead by dawn.

UPDATE 3/18/2017:
After reading my review, InnoGear suggested a fix (wider spacing), and offered to replace the pair. I responded saying, "Let me try the fix before you send replacements."
InnoGear replaced them anyway! This was totally unexpected. Amazing customer service. After 4 weeks of operation, both new units are performing as advertised.
Regarding the old units: The motion sensor is bad on one, and the batteries don't power the lights overnight on the other. These problems do not exist on the replacement pair.

After only two weeks both failed and no longer work. I would not recommend purchasing this.

Both stopped working after only 60 days.  No reason why!!  Just stopped working on their own...Can't return them after only 60 days.  Only have a 30 day return policy.

Two different units.  Both simply stopped working and would not power up after about two weeks.  Serious design or manufacturing issue here.  :(

I loved my first one and then my second one...now on my third and it didn't last more 2 weeks...very disappointed.
