We have had these for several months and have not had a problem with them, charging devices on a daily basis.

These are good.  Our family has been using these for a few months now.  Very reliable.  They feel well made.  Glad we got them.

We find these to work better than other products.

We have bought a few of these and have been very pleased with the quality.

These are not the most vibrant colors, but none arrive dried out and all still work a few months later.

They work great.  Not sure about durability yet.

Had these up for several months now.  Still no bugs, but is winter time.  Will have to see how they do come Spring

We've been through two pairs of these already. The first pair broke in the first two weeks and now the second pair we've had just over a month and are breaking down. I'm not sure if we've just been really unlucky or if it's the headphones themselves. Either way we've had a bad experience with these.

I've only had these for a few months, so I'm not 100% sure on the durability, but so far, they've been perfect.

I bought the very same set last fall 2016 and they are still going strong. This set I bought in May but didn't put them up till the first of October. They are in same spot as the old ones and the solar panels are within inches of each other. They only came on a few times and now not at all while the over a YEAR OLD SET WORKS. Unfortunately I see I cant return after 30 days. disappointed!

I loved these but after several months the cup came apart.  One was dropped so not the company's faults but the others came apart either during use or when being hand washed.  We only used them for drinks without ice.  We do not have a dishwater.

We moved to a new place and bought these, and we haven't had an ant problem. Not sure if it's because of these though

HAve tested several months and seem sturdy and work well. What more do you need?

Not sure if they are unbreakable, but none have so far.

My main complaint with the non-stick I've bought in the past is the non-stick coming off, scratching, and so-on.  I haven't seen any of that after a good ten months of use.  We use them heavily, and are apt to stick a fork or other metal instrument in them on occasion.  We don't make a habit of it, we respect the teflon, but such incidents do happen.  Yet they still hold up, they still carry on.  But nothing like the ones I've bought locally.  It seems I'm buying a new set every winter due to the teflon chipping away, but I won't have to this year, because these look solid and lovely.  You have to know how to use them, but these seem to take wear and tear so much better than many others.  Give them a try, you'll get more use out of them than you will from the regular department store selections.
