Shoddy construction, and at least as far as I've tested it simply doesn't work.

Straight up garbage. First the quality is poor, true to its vintage roots the glass is highly irregular in thickness. I understand this adds, "personality" but it's not the sort of personality you want when the section thickness gets down to what looks to be a few atoms thick at one side. Surely I jest but seriously, it's way thick at one end and thiner than paper at the other. One tiny whack and this thing's going in the recycle bin.

Now the other more pressing issue, it simply doesn't work. I filled it with apple cider vinegar, it's close to a sunny window so it's fuming plenty I'm sure. It's been there for nearly 2 weeks maybe immediately adjacent to the garbage disposal drain which had tiny fruit flies around it. It has...literally...not a SOLITARY fly inside of it.

In my opinion this is poorly made and not functional.

If I could give 0 stars I would, the product does not work

Find one elsewhere or make one.  I had to reinforce it to begin with and that didn't even help.

It could not make it work even though I followed instructions.

I had high hopes for this, and it was messed up out of the box.
The fourth port had it's LED dimly lit constantly, even without a battery plugged in. it refused to charge on that port. A battery swap to a working port proved this. the batteries didn't charge completely either; I had to top them of with the usb charger that came with my Hubsan H107D.
I decided to open the enclosure and inspect the board. I found that on the 2nd and 4th port, the LED's were loose, apparently the pads had lifted from the PCB, meaning whoever soldered this thing either overheated the components in question or the PCB itself was junk. I tried to fix it to no avail. for the price, it's not even worth sending it back for a replacement. I plan on getting a different charging setup; 8 bucks down the drain. The spare props I ordered were nice though.

It simply doesn't work. I put in the batteries, turned it on and got nothing. The unit looks flimsy too. Very cheap plastic.

I bought this for a relative, and installed it in their house.  We're returning it, and not even thinking of getting a replacement.  Here's why:

1. It doesn't work.  Though the base station does seem to make some nice gestures at seeming to work, and it does call out to your phone numbers assigned when you test it, the included sensors can't register on the base station beyond about 5-6 feet.

2. It's poorly documented.  Just in the very first minute of installation, I somehow triggered the alarm, and didn't realize that there is a switch/button under the battery door of the main unit that basically sets off "System Panic" once you remove the battery door.  You have to have the witherwithal to get the cover on neatly, make sure it's snug and tight, then turn the unit over and enter the default disarm codes, all while trying not to soil your pants from the awfully loud noise that this alarm sets off.

3. The door/window sensors aren't very forgiving at all for molding around the doors and/or windows.  It's difficult to mount the sensors and corresponding magnets in a way they'll be flush enough for the sake of the sensor.

4. The motion detector is not so great, and we found it to barely trigger the base unit even 2 feet away.  This, despite replacing the battery to see if it was just an old/pre-supplied battery issue.

This would have been laughable and funny, if it weren't so negligent for the manufacturer.  The only thing going for it is the ability to dial out to pre-assigned phone numbers and play a pre-recorded "System Panic" message over and over after you say "hello" -- without a monthly fee.

But try not to think about the one potential time you actually need the system to work -- say, a burglar or other criminal breaking into your house -- and the system/alarm failing entirely.  It's almost unforgiveable on the part of the manufacturer that these aren't QA tested to be absolutely working.

I bought the system so my relative wouldn't get ripped off by a burglar.  Instead, I feel like we all got ripped off.

Failed to work upon first installation, except for some intermittent activity - seems to be due to a mechanical intermittent in the time/test switch. Unfortunately it's outside of my return window, so I'm out $34 and off to my nearest home improvement store for a replacement. Obviously very disappointed.

It didn't work...or maybe I'm using it w/ the wrong equipment.

Frankly, I just wouldn't buy this product. The concept is good--and it seems to be made of high quality materials. But the way it was engineered actually leads to product failure, rendering it completely useless. It fell apart.

I installed this just as it says.... and was able to use it in my cup holder with my Iphone 6 Plus for a few days. Then, I went to make a slight adjustment to it (move it to the other cup holder, as there are two next to each other in my car) and it made a "pop" sound when I went to tighten it up. The bottom half of it completely came loose from the top half, rendering this completely useless. Seems as though there is a metal rod that goes through the bottom of it that came apart, and it's literally impossible to put the whole thing back together. The metal rod that holds the bottom part of it to the top part can't be put back, so it's now in about 4 pieces. I threw it in the back seat floorboard and that's where it still lays.

I guess if you "install it" in one cup holder and DO NOT TOUCH IT then it will work. But, if you ever go to unloosen it and move it to a new cupholder, then keep in mind that it will probably come apart.

This product was a good idea, but the execution of its construction is poor.  It is responsive, does what it says, works relatively well as a controller.  Problem one was the power, I actually had to send it back to alesis because there was a problem with the jack on the unit.  Not a big deal.  But the pads, while responsive, are a pain to adjust.  The two bottom right pads on mine trigger at the same time (when you hit one, the other triggers too), and I've spent more time trying to adjust this (following the directions) than actually playing the darn thing.  Even when I got it, I spent hours adjusting the other pads so they didn't trigger all at once, but those last two I can't fix.  I can't even trigger them separately in order to adjust them!  After having this for about two years with light use (and, to reiterate, more time adjusting it than actually playing it), I've basically given up on those two pads ever working right.

So far it's not working for me---don't know if it's me doing things wrong or the item that is having problems.

I have been really disappointed with this product. I wanted a vertical stand in order to save entertainment center space and it successfully held the PS4 up, hence the 2 stars, but the rest of it is inoperable after just a few weeks.

Straight out of the box, one of the controller charging cradles would not charge my controller. This was fine, as I only have one controller, so I just used the other. A few weeks later, that cradle stopped working as well. I thought maybe my controller was wonky, but it charged fine with an external charger.

After less than a month, the "cooling" fans stopped working despite my efforts to prolong the life of them by turning them off when not in use. This led me to believe maybe my PS4 had a bad USB or something that was causing all of these issues. Everything works fine with other peripherals.

In addition to the aforementioned problems, the units construction is poor as well. It is made entirely of flimsy plastic and some components like the front USB hub and "cooling" fan on/off button are off center and tacky.

It doesn't work at all and I don't know why. Any support?

Didn't work no matter what I tried, even modifications to the card itself.

I could not get anything to work with it.  Perhaps it is my fault for expecting it to be simple.
