Could have been usable, but...

Just not a good design.  Here's what's wrong:

- Foremost problem with the item I bought... it won't charge my phone.  The little blue light comes on showing that the charger itself has power, but it doesn't transmit power to the USB ports.

- Most cigarette lighters / power supplies are near the stereo and other central controls, and generally placed low.  This means your mounted phone or mp3 player will certainly obscure these controls, and it will also not be in a convenient field of view while driving.  Anytime you have to take your eyes off the road and look down, it invites trouble.

- Unless your car rides like a dream, your phone will be bouncing all over the place any time you hit a bump.  I don't want to subject my electronics to that much vibration.

Even if the charger had worked, I probably would have returned this item anyway.  It's just not a good design ergonomically speaking.

Not so much a complaint about the product as the manufacturer/supplier ... the product showed up in typical/speed Amazon timing, but it was defective (missing one of the threaded inserts to put the product together).  When I went to return/replace this item, Amazon no longer had any in stock and was unable to coordinate with other suppliers to get me what I needed.  In the end, this was a unique and frustrating experience with Amazon ... I returned the product and to go to a local/physical store to get a product that was "correct".

As for the product itself -- it's a bit of a bear to use at first, but once you figure out how your various equipment needs to be mounted it does the job it claims to do (if you're trying to get 6 pairs of skis on it --- it is in fact possible, but everything got to go together just right).  All in all, if you've already invested in a hitch-mounted bike rack AND have some limitation to mounting racks on your roof this item gets the job done.

it was rocky, and missed the adapter as if $50 wasn't enough for this thing, they want to bleed the user for an adapter this generic model. boo.

but it did work well for what it was.

These have promise, and were supposed to be from the newly engineered batch to correct an existing problem.  However, one of these parallettes was not level once assembled.  It appears that the wood bars are attached to the uprights without the entire unit being assembled, and because of this, the uprights were several degrees off from being square.  This results in one of the units having a pronounced wobble.  This could be an easy fix, removing the screws from one side of the bar, leveling it and reattaching the screws.  I haven't decided yet if I will do that or simply return the items.  For $70 (on sale) this shouldn't be an issue that I have to deal with.

... as if this was used already. Unfortunately i noticed it too late and now can not even file a return.

For the most part I like it, I think.  I mean, I'm not blown away though I do recognize that for what it is, this is really a quality device.  Trouble is, right now we live in a sea of Bluetooth speakers.  So in using this, I kept looking for a way this was differentiating itself from the umpteen hundreds if not thousands of other speakers out there, and truth be told I didn't see much that was compelling.

It's a handy device, to be certain.  It's not overly large, with a number of functions built into it as a way to give it some versatility.  There's the Bluetooth mode of course, but there's also a built in radio (complete with cable antenna) and an aux-in as well as speakerphone capabilities.  So it promises to be more than a one-trick pony.

The initial draw here is the plug system, in that you can keep this plugged directly into a wall outlet.  On one hand that's kind of a nifty thing, but then on the other I kept scratching my head with it.  First, the plug on the speaker is situated that when plugged into a standard 2 outlet household drop,, it renders the other outlet unusable.  If you plug it into the top outlet the speaker entirely covers the bottom outlet, and if you plug it into the bottom outlet then it comes right up to just under the bottom of the top outlet, again making it unusable.  So you'll pretty much have to use a dedicated outlet for this...unless you go the extension cord route, but if you do that then why bother with a built-in plug on the speaker to begin with...?

You could also go the charging route, as this device has a built in battery and you can play off that.  But again, there are other speakers out there that do the same thing without the built-in plug.

See what I mean? Head scratching.

Another oddity is the radio.  Oh, not the sound or anything...it picks up radio stations just fine, especially with the cable antenna deployed.  Unfortunately there's no good way to actually tune the radio.  There isn't a display telling you what frequency you're on, so you kind of have to guess.  The default mode is a scan mode where the device will store the first 20 stations it finds.  You can also manually tune the unit, but again since there's no display you aren't always sure what station you're catching.  So this makes tuning and listening a little difficult.

I had best luck and results using this as a straight Bluetooth speaker.  As a small speaker I wasn't expecting full symphonic reproduction, but for what it is the unit did a good job.  It's good enough to where you know what you're listening to, certainly.  Throwing in the speakerphone capability is nice, although honestly I usually stream music from my phone and I don't like when my phone rings and interrupts the music.  I wish there were an easy way to turn that feature off.

It also offers a charging USB port with the built in battery rated at 1,000 mAh.  This was enough to bring my dead iPhone 6 to 50%, in a form factor that's much larger than a higher-capacity battery that fully charges my iPhone 2 times.

So see what I mean?  On paper this device looks great, offers all these features, and so on. But after a time I got the opinion that this device is a jack of all trades, master of none.  I look at it and can't think of one thing it does better than anyone else.  It's not *bad*, definitely not.  But is it something that stands out?  No, sadly not for me.  So I think it's OK...but that's about it for me.

Nice form factor. The tradeoffs in the product design limit its usefulness:

* It's nearly useless on devices with USB 2.0 interfaces
* Its driver can't co-exist with the DisplayLink drivers used by Pluggable and others

Given the price and the design limitations, I'd spend the extra bucks for another device if I had it to do over again :)

Received the unit and I couldn't turn the dials, something inside was binding preventing me from setting the combination.  It was cheap enough that I just wound up tossing particularly when I realized I had something at my disposal already that fit my needs.  Not necessarily turned away from Stack-On products, just didn't need the item despite thinking I did.

Worked with no issue, only come to find out it was not what I needed. oh well. I am sure I can find other ways to use it.

Tore open as I tried to use it, and I was being careful. But still usable.

I bought this thinking that I'd be able to used it as a faux touchscreen replacement (ya ya  .. too much asked for) and obviously it didn't work. I still kept the thing for the novelty, but as I said, all the best in trying to make this work if you intend to use it as your daily device

This was among my first attempts at learning FORTH, and I thought it was a good buy because I'm on a limited budget. Unfortunately, buying it<a data-hook="product-link-linked" class="a-link-normal" href="/The-Complete-FORTH-General-Trade/dp/0471882356/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">The Complete FORTH (General Trade)</a>&nbsp;was a good example of incomplete research - because I didn't realize until after I bought it that finding a FORTH-79 compatible implementation is near impossible. I can't return it though, because the glue in the binding was so old the pages started coming out after I opened it. I'd still like to use it if I could find a FORTH that supports it, because Winfield presents the lessons so well.

Good enough, but didn't actually need. Return was easy, though.

Made CD's for my mom... she's old and used to own her music on 8 tracks and Vinyl. These were awesome looking and I thought she'd get a kick out of it.... until she called me to tell me that it wouldn't play on her record player because the 45 RPM adapter wouldn't fit in the middle of the "record". After telling her to press the eject button on her computer, then put it into the "cup holder", with the shiny side down, and push it back in, she was happy. (and I'm pretty sure she thinks is some sort of sorcery)  Maybe next Christmas I'll get her an MP3 player.... that should be fun.

I thought it could have worked better for the price.

This product would have been good, had it arrived in good shape. However, two of the caps attached to the bottom were not there, leaving two holes in the box, rendering it useless to me. I ideally would have wanted to exchange, but I'm not given that option. Now have to go through the trouble of returning, getting a refund, and finding a new only >_<

...It did not work exactly as I had planned.  First off, the monitors I was using were towards the upper end of the weight limit.  I never could get the far left and right monitors perfectly balanced, there appeared to be a slight bend in one of the arms, the one side was always about 3/4" lower than the other.  That brings me to me second point, the right and left sides need to have the exact same sized monitors, as the stand cannot handle a big weight difference as the arms are extended without wanting to tilt in that direction.  Which brings me to the third point, the side arms cannot be extended too far forward without the stand wanting to fall forward.  I ended up taking the side arms off altogether.  I'm using it fine as a two monitor stand.
