The connected rive was not detected by the cloning software and seems to be a problem with the Sabrent and hence I could not use it for the purpose I had bought but I feel that I might use it for other drives letter and update my rating based on experience.

When I received the unit, it looked like it had been opened and returned (the batteries were installed), but the "pull" tabs for the batteries were not in place.  One was in the box laying loose, the other one was missing completely.

  I plugged the unit into my media computer.  Nothing happened (did not install).  Checked settings (turn off/on keyboard & mouse and try to pair again), but no software loaded and neither the keyboard or mouse would work.  I had a Logitech trackball on the unit already.

  Moved to a new computer (same setup with trackball).  Plugged in the USB wireless receiver (unified).  Software installed for the unified USB receiver (automatically)!  Paired the keyboard & mouse, and checked the software.  It shows 2 unified receivers, 1-trackball, other one with keyboard/mouse.  Unpaired keyboard/mouse & USB receiver.  Ran software & paired keyboard and mouse.  It works properly.  Unpaired keyboard/mouse.
  Return to media PC.  Download unified software from Logitech.  Install Logitech unifying software.  Paired the keyboard & mouse.  It now works on the media PC.
  While it was a hassle to install, it seems to work properly after that.
  Since it looked like it had been opened, I believe the previous owner was not able to successfully pair the devices - like my first try.

This is essentially nothing but a drive connector with cloning software. The connector is flimsy (and needs to be well supported, so it does not lose the connection) and the software deficient.
Before continuing, note that the description is "*Universal* hard drive adapter. Ergo will work with any drive.
The cloning should take place from a Hitachi Travelstar to a larger Hitachi Travelstar. Both are recognized in Bios and are now recognized in the computer (that is the second has been activated, so works on this unit).
Both are recognized by the software. Attempting to clone,  however, calls the error "copying from drives with different block sizes is not supported". In other words, it will not clone drive a(same manufacturer, same line)to drive b. So much for "Universal".
Have run checks on both drives, and both are healthy.
Like many other users I have wasted several hours trying to get this to work.
Since there is a specific error message built into the software, Apricorn is obviously aware of the issue, yet there is no information available on their web site. The information provided in the package is a classic "quickstart" guide with no information beyond what you would need if the device worked properly.

Device would not connect with my year-old PC running Windows 10 with the latest updates. Apparently this is a common problem as the manufacturer has a lengthy troubleshooting document on their website regarding this issue. But even after wasting an hour or so following all suggested solutions, still could not get past software activation due to Windows 10 not recognizing the connected device.

Not the adapter's fault, I think.  It is just not syncing something I wanted it to.  I'm not a technological person, so haven't spent much time trying to figure it out past the initial try.

I connected it up and it saw the device and began looking for a driver
on the net. It looked like it found it, then nothing. The PC never seemed
to see the drive again.

The hardware is nice, the software is where these lack.

The Unifi Controller must be actively running somewhere on the network for connecting devices to inherit the policy of the group they're assigned, if the controller isn't running the connecting device will inherit the connected SSID default policies settings.

Additional SSID's are not connectable after a switch reboot. The AP must be rebooted or the Unifi Controller software must be started.

The software only offers limited configuration with regard to schedules and other nitpicky things.

The connector works great, but the software is useless and its cloned drives were not recognized on 3 separate laptops, use the cable, but download Acronis which for me has always worked.

I turned of the device in the system tray. restart computer and it does not even list the device in device manager. re installed and restarted same issue. Stuck it in 4 different pc's and a mac and nothing happens. Its a piece of shit but at least it worked well 4 a whole 2 months!!

Computers didn't  recognize it. Mine also came with some hair strands trapped inside.

Edit: the connectivity issue was due to a cable wire being disconnected from the circuit board. After resoldering the wires it worked.
Although, the two middle ports fit fine, but the other two have an uncomfortably tight fit. Also, it can't run a mouse and controller at the same time or the controller alone.

It was not attached,  just a long string of links? Don't know how to connect it or put on the new ones?

i plugged in a drive i'd been using and computer recognized it and i thought that i was good to go. but when i plugged a brand new drive into the 2nd slot there was no way to get the computer to do anything with it although it could see it. and believe me, i worked in computers for 35 years, there was something amiss. of course i swapped the slots and put the suspect drive in the slot that worked with the good drive and moved the usb connection around and did all the troubleshooting due diligence. i pulled my old one slot back out and connected it and the computer recognized the new drive and i formatted it. then i repeated all i'd done with the new dock and i came to discover that this dock will not work to mount two drives onto your computer--the two slots are seemingly only for the clone feature which i have not the least need for. but i could find no way to bypass this behavior so it's boxed up and going back. i gave it two stars because, who knows, maybe the clone feature actually works.

Be ready to either configure it manually (by logging into it via your LAN. The login is "admin", and blank for password) or spend some quality time with dlink tech support

Two of the three interconnected. I had to contact first alert about the one that would not interconnect. The are replacing it due it being a defected product. I guess it's better to find out now then later when it's to late.

I followed the quick start guide and have it connected with LAN and I confirmed the camera was working with mobile app. Wifi connection was successful. Then the software does not allow me to login anymore. Only things I get is Login Fail and Open Fail. Very frustrating. It is going back to Amazon. Sorry.

I got the device, connected it, but it didn't work out of the box. I had to download the updated drivers for Windows 8 from their website, and then it started to work. After upgrading my laptop to Windows 8.1, it stopped working again. I contacted the support for the updated drivers but they said they don't yet have drivers for Windows 8.1 and they don't have a specific date when the drivers will be available.

CableMatters contacted me and offered a replacement cable with an upgraded chip. It's working now fine with Windows 8.1 with the updated driver that came with the cable. Good job CableMatters, and thanks for the excellent after-sales support.
