I admit I've had this hub for only a few hours, but I'll be back to update / correct if anything "funny" turns up.It "just works" right out of the box, which is a LOT more than I can say for some (ahem) other vendors' products. The combination of on-board USB 3.0 and 2.0 is brilliant.This is actually called the MondoHub, made by Manhattan Products (per the product insert in the box).My system:***- MacBook Air (2012 model) w/max memory, two USB 3.0 ports and one Thunderbolt port- 10 USB 2.0 devices connected to this hub: four kinds of printers, USB audio, external keyboard with mouse plugged into the keyboard, DVD-RW drive, Epson scanner, 1 Jawbone bluetooth headset in its charging connector, and an occasionally connected iPhone- 3 USB 3.0 devices (2 external hard drives, 1 USB 128gb thumb drive)***I have tested all of these devices attached together to the MondoHub and they are all working perfectly. In particular, the external drives (2 TB each) are doing the critical backups (both Time Machine and other) on the system, and are "talking" to one another and the laptop very reliably.(You can count, so you can tell I have a lot of USB ports still available.)Is it enough to have four USB 3.0 ports? In my case, absolutely. Think about it: what do you need the higher speeds of USB 3.0 for? For data drives, of course. You don't need it for printers, keyboards, audio, and other such basic devices. So why pay for all-3.0 when you don't need it?Plus, by far the vast majority of device types are still USB 2.0 anyway: it's everywhere, universally supported, and very stable. For many years the odds are that most brand-new devices you buy will still be USB 2.0. Now you've got one hub to rule them all. (Sorry, couldn't help myself.)I'm enthusiastic partly because, for many years, I've had to gang together several 2.0 hubs, but with wildly varying results. When I was running Windows, it was pretty ridiculous -- devices dropping off and coming back on for no apparent reason, taking forever to connect, etc. After I switched to a Mac a couple of years ago, things got instantly better. But things were still messy, and I still didn't have USB 3.0.I just did my own personal benchmark, and can affirm that I am definitely getting the same speeds from the MondoHub's USB 3.0 ports as if the same drives were connected directly to my on-board ports on the MacBook Air: 6 mins. 33 seconds to transfer a 9.86 gb file (an iPhoto library) from the MacBook to the external drive. And this was even while the system was doing a large Time Machine backup to the 128gb thumb drive also attached to the MondoHub.I haven't decided if the on/off buttons for each port are a big help or not. (I imagine they would be if, for some reason, you wanted to reboot a USB connection.) And the USB cable from the hub is hard-wired, so you can't just jack in your own (longer) cable. (Now that I think about it, this is a big plus because it means that The Worst cannot happen: the main cable to your hub accidentally slipping out, and trashing all the live connections to all your external drives all at the same time. THAT thought makes me shudder.) OK, so the built-in cable is fine for my needs: about 3 feet long.So far, all I really need to know: it works. (And I was highly skeptical it would.)The only thing that at first concerned me was, on first boot-up after connecting it, my MacBook took a couple of minutes to finally boot. This has NOT happened on subsequent boots, which are very fast, presumably because the first boot involved drivers being configured for the first time.CONCLUSION: THIS IS INDEED THE HUB YOU'VE BEEN LOOKING FOR. I sure as heck have -- for years. It's great to get an item exactly "as described". Thanks to Manhattan Products for FINALLY solving a longstanding personal computing problem that no one else has noticed yet.I will update as new information arises.________________UPDATE - OCT. 27, 2012: Seems to work great under Windows as well. I boot my MacBook Air to Windows occasionally to work with my one essential work application that is Windows-only. I realized I hadn't tested that.As usual with booting to Windows, I found it best to first unplug the hub from the laptop, then do the boot-up. (As with all other hubs I have used in this scenario, if I boot with any hub plugged in, Windows takes FOREVER to boot up. Plugging in after the boot clears that up.)But, once booted and plugged in, all devices I tested work fine: trusty black-and-white laser printer, external sound card, keyboard and mouse combination. But, most importantly, ALL of my USB 3.0 external drives were there (as well as one USB 2.0 drive that I keep formatted for NTFS). I certainly don't use all of my USB 2.0 devices under Windows (as I only occasionally need Windows), but the tested ones work great.So, I continue to say about this hub: Go for it!________________UPDATE - MAY 28, 2013: Not much new to report except that all is still well and working as described above. As the manufacturer notes clearly in the product documentation, this hub (like all others I've seen) does not output sufficient voltage to charge an iPad. With an iPad, you are always best off using a dedicated iPad charger, or your on-board USB port. Still a great hub and very glad I found it.________________UPDATE - Sept. 11, 2013 - USE THE GREAT MAGNET MOUNTSThis hub comes with magnets embedded in the feet on the bottom. I bought a 12"x12" While you get "28 high speed USB outlets," you only get 4 USB 3 outlets. Maybe I missed it in the description, but that was not the impression I had when I ordered my Manhattan. Also, while there are numbered switches to turn on and off each outlet, none of the outlets are numbered and so you have to figure out by trial and error as to which switch goes with which outlet.The unit comes with rare earth magnets on the bottom to attach the unit to a metal cabinet. This seemed pretty cool. The only problem is that the magnets are held in place by their little bitty magnetic fields to small screws. Three of mine were loose in the packaging and when I attempted to replace them in their holes, I passed too closely by a couple of the other magnets and sucked them out of their holes. In short, the magnets need to be glued in place to work properly. Otherwise once you stick the Manhattan on a metal surface and try to remove it, all the magnets remain on the metal surface because the metal surface has more surface area than the little screws on the unit. So the magnets are a waste if you don't glue them in place and it is probably best that they be removed if not glued in place so that they don't potentially corrupt any of your magnetic media (assuming you have any that is loose and susceptible to magnetic fields). All my magnets are now holding pictures to my filing cabinet.Otherwise, the unit seems to function just fine. I definitely had to add on the (included) power supply in order for the unit to charge up my cell phone, but that certainly worked as designed. I needed the Manhattan for the additional outlets and it is doing the job as desired. Given the cost of the unit compared to some others, it seems to be a reasonable deal. If you need more than just 4 USB3 outlets, however, then this unit is not for you. If you are like me and have mostly USB 2 peripherals, cell phones, cameras, external hard drives, thumb drives, etc., then this unit is very handy!I have a ton of USB devices that I regularly use and hate having to reach around the PC tower to fun a spare plug, most of the time I'd have to unplug something else to make room.I finally got sick of it and saw this massive USB hub with 3.0 support and instantly purchased it after seeing a lack of other options, the price was right also.Upon receiving the unit I put it to use right away but plugging in four bitcoin miners, usb gaming headset, usb 3.0 cruzer thumbdrive and what can I say other than every device was recognized right away and I had no power issues.I love that this unit comes with it's own power supply to augment the usb connection to the computer, most of the small usb 2.0 units I bought back in the day always had a barrel connection for one but it was almost impossible to find a wall wart that would work with them so this was awesome addition.I'm giving this item four stars because of something that might not be important to most but it was to me, the bottom of the unit has four magnets on the bottom that are glued on very cheaply I guess because within about 30 minutes of use two stayed on the side panel of my case when I bumped into it fiddling with things, seems like something easily taken care of by little bit better design or manufacturing but it doesn't detract from it's primary function as a giant awesome usb hub.Using this non-stop since purchase (over three months I believe) it's never had a single problem, I highly recommend this for anyone with lots of devices.While listed on Amazon UK, this doesn't come with an appropriate power adapter as stated in the description.Im Vergleich zu verschiedenen anderen kleinen USB Schalterleisten hat das System was solides. Die Funktion ist erstklassig, die Schalter erfüllen ihre Funktion, das Netzteil ist leistungsfähig. Man könnte sogar 5 Sterne vergeben, wenn nicht zwei, drei funktionale Lösungen etwas gewöhnungsbedürftig sind, oder besser sollte man sagen: idiotisch.1. die Beschriftung der Schalter in zwei verschiedene Richtungen vorzunehmen ist eher Blödsinn.2. es wäre besser gewesen, alle USB Buchsen in 2er Ebene an einer Seite zu positionieren und zwar horizontal liegend. Die Stecker nach oben zu positionieren, führt zu einem Kabelsalat, wo man aus schräger Blickrichtung sehr aufwendig wird,3. die an der Unterseite eingelegten Magnete für die feste Positionierung sind nett gemeint, aber solange man diese nicht anklebt oder anders fest positioniert, kann man darauf verzichten. Besser wäre eine Öffnung für die Fixierung mittels Schrauben oder eine umlaufende Kante für eine Befestigung mittels einer Schraubzwinge.Ho in linea 7 hd fissi 3,5 (6 usb2+ 1 usb3) + 3 hd 2.5 (2 usb2+1 usb3)+ 1 masterizzatore usb2+3 stampanti. Inoltre ho spesso da collegare la mia camera usb2, il mio recorder usb2 ed un certo numero di chiavette. Fino ad oggi gestivo il tutto con una serie di hub acquistati negli anni. Naturalmente mi ero costruito anche un cavetto per alimentare la ventola dotato di interruttore da lampada. Ogni volta chiedevo inutilmente se c'era qualche hub con almeno uno switch.Potete immaginarvi la mia soddisfazione quando ho collegato il tutto a questa meraviglioso HUB (questo sì maiuscolo !) a 28 porte e vederlo funzionare perfettamente. Sembra caro, ma il costo per porta è minore degli altri.L'unica noia è stato il volerne collaudare tutte le porte al suo arrivo, l'ho riempito di chiavette controllandone il funzionamento una per una !Brava Amazon e brava Manhattan !Ho inserito tutto quello che avevo come periferiche usb (mouse e tastiera del desktop comprese)e tutte vengono lette e riconosciute.Dall'uscita (usb 3.0) ho dovuto usare una prolunga per connettere l'hub alla porta usb 3.0 del pc ma tutto l'apparecchio funziona.Se si collegano anche mouse e tastieria consiglio di alimentare l'hub prima di accendere il pc perchè non vengono riconosciute subito.Era meglio però dato il prezzo che vi fosse qualche porta usb 3.0 in più (sono 4 + 24 2.0!).Naturalmente quelle che non servono si possono tenere spente e accendere solo all'occorrenza.Venditore molto attento e preoccupato alla vendita e questo è un fatto molto positivo malgrado qualche responsabilità del corriere ma erano anche le feste natalizie.Having a professional level flight simulator with literally dozens of USB connectors, makes this an essential add on. Each usb port is individually selectable which might be handy for some applications. MISSING - is a master on/off switch for those times I need to reboot all the USB ports because Windows 8 is doing it's strangeness with USB ports. In that case I need to crawl in and unplug both the USB power source and the wall-wart to ensure a cold restart. meh.
