Works in a pinch, but rather have different all in one device

Often have trouble reading SD cards with this device and that is primarily what I purchased it for. After a little jiggling and fuming over the card not being read a few times it FINALLY worked. If I wasn't in such a bind for the data I would've given up on this long ago. I now have a MUCh better device which I posted a review for also.

It's alright, but can be frustrating when you want to connect to both wifi and the usb - the stick requires that you connect to it as if it were a source of wifi, disconnecting your device from whatever source of actual wifi you have

Works as advertised, but not as useful as I imagined it would be.

Functionally OK. A nice feature is that you can re-orientate it depending on your hardware configuration needs. This item will not power more than one or two connected devices, so it's not good for charging multiple mobile devices unless you only use one or two depending on the device's current demands.  Other devices can be connected simultaneously if they have their own power source (battery, or power pack). This should work for low power human interface devices or wireless transmitters,a WiFi adapter, or flash drives.

For starters, this is a good solution for those with a tablet and a smart phone, but the devil is in the details.  The tradeoff of one outlet for two powered USB sockets is a fair one, and having one be full power and the other limited in output is common.  That being said, it's not what I expect from a device of this caliber, and compounding things, each socket works differently without being clearly labeled.  Make both ports powerful enough to charge anything (this is targeted at early adapters, right) and it would get 5 stars.

Pros:
UL listed in a sea of products of questionable quality
solid build
smart chip

Cons:
no wall plate (really?)
limited power output
two sockets work differently
cost

Works great in a homogeneous network, so it is unknown if it will play well with others. The hard-coded passwords for making some changes is difficult when devices get installed in "out of the way" places, so make sure you keep tabs on them before you install them. The configuration utility is not very friendly on high DPI devices.

had to use inclusion mode on my zwave device because it didn't normally pick it up, but works as designed

I was going to use this to hook up my Xbox One and my computer to the same monitor. It works as I hoped, but I'm getting a lot of fuzzy feedback when both HDMI cables are plugged into it even though only one device has power to it. If only one cable is plugged into this, it works perfectly. At this point, I basically paid for an HDMI extender.

I gave this USB hub 3 stars because I found I had to pick and choose the accessories I plugged into it.  I found through trial and error that only certain components I use would be recognized by my computer.  I do some gaming and have headphones, a joystick etc. plus all of my standard computer accessories that utilize USB connections. printer,keyboard,mouse etc.  Certain components plugged in and were instantly recognized. Others when plugged in ceased to exist and were not recognized by my computer necessitating a bit of switching and swapping of USB connections to get everything recognized and working. The USB hub fulfilled it's purpose of expanding my ability to add extra components. Just not with the ease I expected. I am by no means a technogeek so I may be missing something simple and obvious. I've had this hub for about a month and it has worked without issue since installation.

I bought this thing for one purpose only: wireless bridge. I was delighted to find affordable device that can do pretty much everything one might need in the wireless networking, though. Generally, I like dedicated devices for single purpose only, but the price here (after offered rebates) was much too tempting. Long story short: it works as promised. There was one thing that puzzled me though, after I tested it: there is only one MAC address for both interfaces (wireless and wired).
This gadget is not for average user and I doubt that this thing may do well as wireless access point/router or repeater for the simple fact that antenna is integrated and one can't expect decent wireless signal coverage; not that I can support this claim with comparative tests. However, as a bridge or wireless adapter (for desktop) you'll get your money worth. Four stars is for the level of skill one needs to get this thing working right - forget accompanying CD/software or booklet.

It works.  The problem is in the fine print.  The switch works best when the connected devices can be fully powered off.  None of mine can, they are all putting out some power when connected so the switch automatically goes to the wrong device.  I ended up just leaving the main device (cable box) connected to my single HDMI port.  That was a disappointment.  When I want to use the DVD player or ROKU I will have to unhook......anyway, the device was a disappointment, but since it was cheap and it kind of works, I'm keeping it.  Maybe I can give it someone else.

An elegant, simple, high-functioning, connected device

works fairly well, drops signal occasionally as well as being unable to handle more than two devices at a time.

This switcher does what it claims to - switch between up to 5 HDMI inputs if your TV only has one HDMI feed.  Note that it does NOT switch automatically, you have to switch between the inputs manually using either the button on the box or the little remote that comes with it.

However, there are a couple of gotchas.

1. If you have a combo DVD/VCR unit, it may have both analog (RCA) outputs and an HDMI output.  With most of these devices, the HDMI outputs ONLY when it's in DVD mode; the VCR plays out only over the analog outputs because VHS is not digital.

This means that, if you want HDMI DVD output and to use this switcher, you'll have to use BOTH the HDMI and also the RCA jacks used - the HDMI to view higher-definition DVD playback, and the RCA for the VHS videotape.

Which works, except that there seems to be some sort of ground loop.  If you're playing back a DVD but you're viewing it on your TV via the analog input, you'll get video jumping and blanking.

You can fix this either by watching DVDs via the HDMI input on your TV (which is what you probably wanted anyway), or by making sure that this HDMI switch is set to an input other than the DVD player when you're watching DVD playback over the analog connection.  Not a big deal, but a potential source for complaints if you don't do it right.

2. HDMI does not automatically resync when you change the TV input, at least for my TV.  What this means is, you have to change your TV input to HDMI, and THEN make your HDMI selection on this switch box - EVEN IF the HDMI input is the one the box was already set to!  Re-selecting forces a resync; otherwise you just get a blank blue screen no matter what.  Again, the solution is easy enough but could be a potential annoyance for non-detail-oriented users.  E.g. wives.

To sum up: this switch box works and is dirt cheap.  But it's not terribly user-friendly when it comes to some of these details.  I wish I could recommend a better-designed one but I can't; the rest of the boxes on Amazon seem to have similar glitches and be much more expensive.

Oh well, maybe as the technology is matured it'll improve.

I had an HDMI port go out on a TV, so this HDMI switch lets me use multiple devices at the same time.

It does the job fine, though I do find that it's a bit annoying because you can only only switch between different inputs if the device is turned on so I can't set it to a specific input unless that input is turned on.

Not the greatest design, in either hardware or software. But it works. The software interface especially can be confusing, Follow along with step by step instructions for USB sound adaptors (easily found online), the specific brand is not important because these cheap ones are all very similar. I had to uninstall and reinstall the driver a couple times to get it working right.
It successfully allowed me to send two separate audio outputs at the same time. Used with DJ software, this means you can run the live performance out of your regular audio jack, then plug your headphones into this USB sound card adaptor, where you listen to a completely different track as you sync up the tempo and beat. This works even with a tiny netbook.

This works but you need to get up to turn the HDMI you want to use since they can't be used at the same time. This is not what I wanted it, since I wanted to have 2 HDMI ports that we detect which device I had on.
