Works great.  Had a couple connecting hiccups, but worked in the end.

Works great.  Only quibble was when it was received, it suffered a minor entanglement due to one of the wires being broken in one spot.  Easy to remediate, but should not have occurred.

Works great with my 2015 Macbook Pro (High Sierra). Have it going through a non-external powered USB 3.0 hub too.

Cheaper than alternatives, especially by Apple, and honestly wanted something USB so I don't have to keep plugging a bunch of cables into my MBP every time I'm at the desk, just my USB hub with everything else plugged into that already.

Things worth noting though and why I took a star off:

1. Installation was weird, used the download link on the product page (few paragraphs below the price), everything installed fine. But it didn't work. It would detect the device in System Report, but it wouldn't recognize I had a cable plugged in. I reinstalled the drivers again, and it worked.

2. The drivers aren't signed and recognized by Apple. It's not even by Amazon, it's using a Taiwan / Chinese manufacturer that I've never heard of. When allowing the drivers to install in Security settings, you just see a random name "Hua La Le" or something. Fine, go for it. But it kind of sucks since I'm installing a driver without knowing what's in it, and some loose connection with Amazon.

Works pretty well.  Once in awhile one seems to lose its connection to the base.  Other than that, it works great.

Works great. I would have given it 5 stars except the documentation was a little limited and that led to extra time for troubleshooting. All schematics show tying the ground wires together for the display and monitoring wires which I found to be problematic for my setup. I am powering the display with 5v and monitoring the current wires are connected to a 36 volt power supply for a CNC machine.

Product worked great then began to have its hiccups last month. It would begin to freeze up and not respond to either the remote control or even the physical buttons on the box. I would have to Unplug it to get it to shut off.

When it worked, it was easy to set up. The remote controls volume and CC also, so that was a nice touch too not have to fiddle with extra remotes while watching tv. It even has an auto tune function to allow you to go to a set show at a certain time of day.

I used this on an older tv that lacked a digital receiver for OTA channels.

Had it lasted longer I would be more satisfied with it. For the price, it offered a good solution without having to buy another tv.

The original unit that arrived had a problem in that it would connect and then disconnect over and over.  I would not have noticed right away except for the sound of it connecting and disconnecting.  It took me a bit to figure out what was doing it as this was a new computer setup.

I sent a note to their support asking what I should try to fix thinking perhaps a firmware update or something and they sent me a replacement unit that they pre-tested to me which works great.

GREAT SUPPORT!

As for the product, other than the bright blue lights (looks like an space console with all the lights everthing has now days in the dark) it works great.  Most of the devices connected are USB2 but I do have a USB3 device connected now and it works well.

Switch works well but the connections are a little glitchy. If it's not sitting just right the signal doesn't work or becomes fuzzy.

Works great. Others have described a problem with this device automatically reconnecting too aggressively; I have only experienced this problem with my older bluetooth devices. My newer devices only automatically connect if 1) they previously disconnected after going out of range, or 2) I turned bluetooth off and back on. Otherwise, they disconnect and stay disconnected.

Works great. But sometimes I have to finagle the connectors to touch to get the charge started.

Works well, but some hiccups. You must be careful about interferring on the process. You must reset the count if you have a hiccuor the coins just pour out. Ehen you start again.

I've encountered a few bugs while using this, although I'm not sure if they are caused by the product, or if they are bugs in OS X.
After turning my second monitor off, the screen flickers a few times but then acts as though it was still on. My mouse moves off screen and I can still drag windows away.
Other than that, the adapter works fine. Its a bit of a tight fit on the HDMI side but that doesn't seem to affect its functionality. Good deal.

I was a little worried about some of the reviews I've been seeing. But this thing works great and the only thing I've had a problem with is sometimes it doesn't sync quite right. There's a very high pitch ring. I just unplug it and plug it back in. No sweat.

Works great, needed to tape prevent it from falling off connection

I bought this adapter in order to fix a specific problem I was having (unwanted flanging effect when recording with the mic plugged directly into my computer).  It did exactly that.  So far, I am satisfied.

That said, there are a couple of things to keep in mind, at least when using this with a Windows computer:
-it will take some fiddling with your microphone options to get the input volume right - there was a lot of noise the first few times I tried this, but once I got that figured out it was fine
-for some reason, Windows thinks that this thing does playback as well as recording, and might automatically set it as the default playback device.  The result of this is that when the adapter is plugged in, you don't get any sound through your actual speakers.  This can be fixed easily enough by changing the default playback device in Windows; it took me a little while to figure it out, but hopefully this saves you some trouble.

Works well.  A little cheap, but it was inexpensive

I like it and it works well now. Bought it for my brand new tower. I was experiencing severe issues when using my usb 3.0 port. The device would connect and disconnect every other minute. Once I plugged it into my 2.0 usb port it worked fantastically. I understand this could have been an issue with my computer but I can't ignore what I experienced. I love it right now, since it works reliably now. I've had no issues connecting to strong wifi.
