Faulty in design or manufacture.

This is the only Sabrent enclosure that I have found fault with.  It needs either re-engineering or its manufacturing specifications need revising.  I found it almost impossible to get it open and, after installing a hard drive, impossible to close it again afterwards.  It is now functioning fine, but  the two pieces are held together by the crew chief's reliable old assistant: duct tape.  Stay with the company's aluminum enclosures; they work well.

I am returning this item for a replacement. Check the reviews, I'm not the only customer this has happened to.

As arrived, the instrument is virtually unplayable. The electronics failed, possibly a bad pot, The tuners were loose due to stripped screws, The intonation was also way off.

I gave this 3 stars because it was, IMHO a great concept, quite nicely made for the price and has great potential apart from the manufacturing flaws noted above. For a few dollars and a few hours work I could have improved the instrument but no my yob! Fixing the intonation and action would require removing the bridge.

Hopefully the manufacturer will improve quality control and market an instrument up to it's full musical potential.

In addition, I assume some of these units were better than others so you may luck out and get a good one...China is like that.

It could have been a great headset. It is not too heavy; it fits comfortable; it has convenient controls; the sound quality is very good; microphone is great; wireless range is pretty adequate...

But, unfortunately, several design flaws turned this potentially great device into an almost unusual piece of junk. Here are the problems:
- This is a wireless device, and, therefore, it has to be charged from time to time. However, though the device charges from USB, you cannot use the headphones while they are charging. And charging from empty to full takes several hours!...
- ... And you will have to guess when it is time to charge it! There is no battery level indicator. So the only way to play it safe is to charge the thing every minute you are not using it ...
- ... Or it will die without any warning. Seriously, I expected it at least to beep when the battery gets dangerously low. But no, the headset just silently died in the middle of a conversation.

There are some other small annoyances. For example, the USB plug blinks constantly when the headphones are turned off, and shines a steady bright blue light when the phones are on. In other words, there is no way to remove the light, and sometimes this gets really irritating.

The USB plug does not attach to the phones, so you have to carry it separately - and risk losing it.

In general: don't buy it.

Antenna wobbles on the base. This design problem should be fixed.

Great feel and look of tablet but extremely faulty design.  When the tablet is flipped open the magnet triggers the tablet's on and off function.  Makes it extremely annoying to use in bed or hold comfortably without triggering the screen off.

Obviously quality control and safety of customers ins't a priority of this manufacturer. I plugged this in with the switch in the off position and it sparked and emitted smoke. If the company tested this before boxing up and shipping out, the spark would have happened before it got me. Someone ordered this for me off of my wish list but I will be returning. If multiple reviewers are reporting this, there is obviously a major design flaw.

I am a professional electronics engineer, I design products for a living, so I know a good design from a shoddy one. And I was amazed to find a critical flaw in this VERY expensive portable refrigerator. I actually expected more from Dometic. The issue will not affect all users, just some.

We just bought this product to go up to Oregon for the total eclipse of the sun, and everything was fine in the beginning. Then, in the course of the trip, the product suddenly went haywire, with the display going off and the internal temperature rising 10 degrees. We would set it for 34 degrees and then I would look later at the display and it would say 44 or 54 degrees. We were running on 12 volt power directly from the van's battery.

As an engineer, I wanted to figure out if we had a bad product or not. After much evaluation, I discovered that using a CB radio in the van screwed up the microprocessor system in the refrigerator and caused the temperature to rise (and the display to blank out). You had to unplug the refrigerator and restart it to fix this problem. This will happen with any transmitter in your vehicle, such as a ham radio or other communications set-up. It seems Dometic forgot to put filters on the power input lines and any RF energy leaks along the power lines and scrambles the micro.

I would expect this from a cheap Chinese product but NOT from a German made product. The product needs POWER LINE filters in an auto set-up. This is auto design 101! This would cost Dometic perhaps 50 cents total and they should have tested the product in REAL life conditions, in a car with a CB or ham radio, but I am sure they just tested this in a lab. Poor design ethics.

If you have a transmitting radio in your vehicle and you want to use this product, you need to add RF chokes or ferrites to all the power input lines, as close to the refrigerator as possible (and UNPLUG the AC cord, which can act as an antenna). I am opening the refrigerator to add RF filters on the power lines on the internal PC board.

A sad statement about the vaunted German quality. For $500+ you expect more thought in a design.

received faulty product. one earphone connector would not provide sound unless held at an angle. fault is certainly with the cable, not headphones as switching the earcup plugs made the other side stop working.

There was no air coming out of the surface, so I looked underneath and realized that the fan was blowing in the wrong direction.  Problem arose because the leads were attached in the wrong orientation. And since all the connections are soldered there is no simple way to fix it.

Did not work as advertised or described in manufacturer's write up.

Didn't work properly, I had to return and order another one.

This is a beautiful looking product and the sound is certainly excellent - but it has an appalling design defect. It is the kind of defect that makes you worry about the rest of the product on the long term. At the bottom of the player there is a rubber strip that sits over the sockets for the micro SD's and the socket for connecting to one's computer. This rubber strip is secured to the device on one side and it flips open to enable access to the Micro SD card card slots. The strip sits flush and cleanly on the device when you get it. However, once the micro-SD is inserted, given that a tiny sliver o the micro SD sticks out of its socket, the rubber strip does not close and hangs loose. It is absolutely awful! It is one of those things which is a hygiene factor the ruins a products experience. Very disappointed.

Unfortunately, the product did not work, I had some manufacturing problem ... I had bad luck, if I had reviewed in the period of change
I would  have returned.

Design has problem that left and right earbuds are not symmetrical. it couldn't be adjusted and not fit ear well.

These look nice and are a good size for small embellishments.  That's it for the good news.  One star is generous.

Each clothespin in the bag I received was defective.  Yep, I tried every single one, as I could scarcely believe that these clothespins were so poorly designed that absolutely none functioned correctly.  I mean these are clothespins, not industrial strength aeronautical clips holding the space shuttle together.  How can someone botch this design?  These things have been around since 1853 -- yes, I Googled it.  The best explanation I can offer is that these clothespins suffer from a seriously faulty design.  When you pinch the clothespin to open it, it twists so badly that it throws the entire pin horribly out of alignment.

I bought these for crafts, but they are worthless for that or any other purpose.  I got them as an Add On item for roughly $5 so they cannot be returned; but its really about the principal, not the money.  I wonder how can someone sell a product like this that they must know doesn't function properly.  Unfortunate.

Please save your money and find a better alternative.  These are just not worth the effort, or the $5.

When actuated, top of dispenser wobbles wildly on its base as if it's broken.  Only it isn't broken, just poorly designed.  Should have returned it, but was too busy to uninstall.  Dealing with a really poorly executed soap dispenser every day instead.
