The device worked great for the first week

The device worked great for the first week, and then one of the plastic "bumpers" practically melted which made the device noisy. I rotated it hoping that I could get some more use out of it. Nope, the "bumper" was nearly disintegrated after only 3 weeks of use (30 minutes to an hour per day, 5 days a week). Then, today, the metal peg the "bumper" presses against completely snapped off. I did write to the manufacturer, and they gave me a full refund--didn't even ask me to return it. I would still not recommend this product.

Worked well for the first week, but now there is a loud, bassy "thump" when a device connects, and every time I pause or stop my music. It's very strange. The product still works well I guess, but its not as seamless as I thought it would be.

Lowered my score since the problem is getting worse.

It worked great the first week, but then the screen went black and it is impossible to see what channel it is tuned to or what song it is playing.  It may just be that mine was defective since there are so many positive reviews, but I can't contact the company to find out!  Don't waste your time or money on this device from this company.

Worked great for about a week and then the voltage readings stopped working.  Submitted a support forum report.  Adafruit claims 'immediate' response.  That hasn't been my experience.  No idea if there is a fix for this situation or if the device is broken.  As is, the device is useless and I'll be seeking a refund.  Too bad because it was sweet while it worked.

When I received it, I LOVED it.  It has tons of option for the low price, the touch screen worked flawlessly, and it was nice and light.  Its super thin and fits great in my hands.  However, after two weeks of light use, this device simply quit working  I was trying to use a camera, and the app won't launch it, so I powered off to reboot.  Well, once the power was off, it never came back again  I have charged battery to make sure everything was set properly, I even removed battery and sim to make sure.  But nothing it was dead.  So I returned it  I was very disappointed because I really liked the unit otherwise.  I am afraid to purchase another one as I don't want to experience the same thing down the road I guess I just have to look at Nokia or some other more recognized brand  Too bad

During the first seven days it froze twice during rides. Also, whenever I tried to connect it to a PC I would get a message: "Device not recognized".

The device stopped working about a week after it was received. No problems with the return. They even paid for the return shipping.

After only one week of use, the hard drive is no longer recognized through the USB 3.0 connection and I cannot access any files stored on the device.

Worked great the first week. Now the sound breaks up if my phone is more than an arms length away. When I put it in my pocket it disconnects.  I'm using an Iphone 6 and have done a hard boot, I even tried using it without my fitbit.

Worked for a week, then died.  Now, for that week, it was insanely fun. Me and my kids would run around the yard trying to kill as many bugs as we could before we jumped into the pool. Battery usage was pretty decent, so I thought - then the device just died. I replaced with fresh batteries, and the light came on, but the wire mesh would not spark. Now, I don't advocate doing this, but I touched it with my finger and still nothing. Returned to Amazon without any problem.

It looks like all of these types of products are hit or miss. Next time I will be buying the cheapest thing I can find and assume it will be a one time purchase. Be warned.

This item was off to a great start.  The interface is the same as the PSP, so I was somewhat used to it.  I used it for viewing blurays, which it did very well for the few that I viewed, as well as for Netflix and Amazon videos.  I actually preferred to use this item for videos because my TiVo has me wait to download Amazon videos and the Netflix quality was much better.  I used the WiFi feature of the player, and never had a problem with a lost connection or slow connection (can't say the same of my other streaming-capable items).  However, about two months after I had the unit (which I used maybe once a week) it suddenly would not turn on.  I unplugged it and plugged it back and it would then turn on.  Gradually, I would have to unplug it more often before it would finally turn on.  Now three months later and the thing won't turn on at all, no matter how many times I plug and unplug it.  From what I've read this is a known issue, and because I was out of return options with Amazon (and I stupidly did not buy a Square Trade warranty for this, thought it wouldn't matter much because Square Trade requires you to go through the product warranty first) I contacted Sony support via their website.  The forms were easy to fill out and apparently it is a known defect because they sent me almost right away to the return item page.  However, I am very upset that I have to pay for the shipping to their repair center!  This is a manufacturing defect and I have to pay for their bad quality item.  In the past I would always try to buy Sony items knowing their reputation, but apparently that reputation is no longer deserved.  It may be just this one item that was a dud, but I don't think I will be purchasing from Sony again.  I have a Samsung bluray player (not 3D) that is over two years old and is still working like new.  Save yourself the trouble and buy another player with a better reputation if you can.

UPDATE: I tracked the item that I sent to Sony for repair and found their website said they didn't receive it.  When I tracked via the post office, it had been delivered on 1/14.  I emailed them and was told that it would not update as having been received until a technician started working on it.  On 1/18, I opened my front door and there was a large box sitting on my stoop.  Inside was a refurbished unit that had been sent out on 1/15.  They must have a stack of these waiting for the duds that are returned to them.  So I hook that up and it turns on for about five seconds then dies.  The same problem I had before.  I tried it in various power strips and outlets around my house and the same thing happened.  I tried Sony's "live chat" option; after telling the person that the unit wouldn't turn on he asked me what error the drive was giving me.  That upset me a bit so I again said that it just wouldn't turn on.  Then he tells me to "turn the unit ON."  At that point I called him an idiot and disconnected the chat.  I then called Sony's customer relations phone number, and spoke with someone who said they would do a replacement on the dud.  Then, he tells me that I have to pay to ship it back to them again.  At that point I almost started yelling at him that I was not going to pay another $20 to ship their second defective unit, and he kindly transferred me to the repair center, where the rep there emailed me a label to ship it back prepaid.  Think carefully before buying from Sony and having to deal with their product support, it's not worth it in the end.  I took off another star for this ridiculous process that Sony has to repair their own lemons.  Hopefully player #3 will work as advertised, though I don't have much hope of that.

Cannot open nor close any longer.

When it first arrived, I loved this device. I am an Uber driver (on the side) so it made it very easy for me to reach over and tap accept on my phone. Unfortunately, within a month, the charger stopped working. I tried my car charger plug in both ports, as well as a standard USB-C cord in the USB slots, to no avail. Now I am just using this as a phone mount, and plugging directly into my car's cigarette port.
