It stopped working less than one year of use. I had to spend quite a time to determine whether it was computer, monitor or the cable problem. Eventually I found the cable was the culprit.

It simply stopped working today, after a year of use. I've never dropped it, never had any issues with it, only use it occasionally. Not worth the money for something that quit working...

Worked great for one year, then it stopped.  Trying to get a replacement. I will update review if and when I get a replacement unit.

It is dead in less than one year!  It was used lightly only.  It stopped charging any devices even though the battery is fully charged, with full bars.

It lasted one year and stopped working. The display would zero out it showed all the values as if in test mode.

Less than a year and the sensor stops working. It is very very random and just as random when it starts working again after 10-40 seconds.

After owning this less than 2 years it's has stopped working (light usage, maybe 30 hours total), it will not power on. It was awesome while it was working, not so much now. Very disappointed.
We used this more for ambiance than heat...now the question is, do I buy another one or find something else?

I had received this product as a gift and it worked for a year the stopped. I liked the function and since it is not expensive ordered a new one.  I connected it properly and it worked for a few seconds then stopped working.

These stopped working in less than one year of minimal use.  Replaced all the batteries, red lights turned on both units, but did not work.  Garbage.

It was ok while it lasted, but less than a year after purchase with only minimal use it started working only once every 4 or 5 times. Now it doesn't work at all.
