Died after few months of rare use.  Dissapointed in this product.

Worked fine for several months. then just died. The red light does not light up when plugged into any outlet. Have contacted customer service since there is a 1 year warranty and have been forwarded to the Amazon Basics team. Will change review if they replace this item. By the way, there is a 24 page warranty on this little item. Crazy.

Worked okay for a few months, there was always a very subtle static in the background while playing from any device on my home stereo system. It stopped working after about 5 months of very limited usage. I may have gotten a defective product based on all the other positive reviews, but that is my experience.

It was great while it lasted, but unfortunately it died at about the 10 month mark.  I had to go one star because I don't consider this to be the sort of product that should be replaced every year.  During the 10 months that it worked it did great, was able to push good sound out to my ATH-M50X and AKG K7XX on the go.  I used it both with a computer while I was working, and with my phone and tablet.  Then all of the sudden, I plug it up and get a ton of scratchy static and it is now unusable just like that.  I'm contacting Amazon support about a warranty replacement, but I can't seem to find anything official for SMSL either.  I would avoid, there are luckily other devices out there that are still somewhat close in price but considering how many reviews I've now seen with this same problem I'm not sure I'd ever buy anything from SMSL again, not worth the risk.

Died in less than 5 months, in a laptop that is used only a few hours a day and is rarely moved from its location.  Not sure exactly how to go about pursuing a warranty repair -- Amazon, Eonline or Western Digital.

Worked great, used a handful of times over six months, battery lasted forever, and then they just died :/

It worked perfectly for a whole 3 or 4 months before it randomly died (despite never being thrown, crushed or otherwise mishandled).
Not worth the $37 I paid for it.
If you look at other reviews, you'll see it's common for these to have a very short life. I won't be purchasing another.

I bought 2 and one died just short of 3 months.  Not cheap if you have to replace them.

It worked beautifully, able to charge several devices on a single charge.  However, 6 months later it died and we did not use it every week.  If it wasn't for the short life I would have given it 5 stars.

Great for a while and then died. Waiting on manufacturer to handle support.

That about sums it up-- we used it a few times a week or less for 3 months, maybe a total of 12 times. Then it just died, for no apparent reason and of course the return period is over. Buy at your own risk!

This machine worked fine, for such a small, inexpensive unit, until it died after 6 months.  The DVD started scraping against the interior of the unit and no longer could play DVDs.  The 90 day warranty was up, so the best Polaroid could offer was another unit for about 30% off.  I suppose I shouldn't expect these things to last very long.  Will probably throw it in the trash.

Only lasted a few months with minor use (like an hour or two per week).

Worked fine for 4 months then died. I have no idea who to contact for warranty or if there is one. Past amazon return period.

It worked for about 4 months and then stopped completely. Bought in October 2017 and it was dead by February 2018.
