Works great for keeping your medicine ball in place so that it doesn't roll all over the place.  I've got a 10-pound ball and it doesn't move a centimeter.  Would recommend.

I did not use this unit for its intended purpose. It is working great for what I am using it for.

It worked great, however, my son picked up his laptop without knowing it was attached and the plug got damaged so I will need to get another in a bit. User error, for sure :/

I got it, configured it quickly, and its up and running. It works as described but has plenty of glitches to annoy most people:
*unit will not run while charging from USB port, it turns to review/file mode only (assumes its plugged into computer to retrieve files), one has to have it plugged into DC power which takes up a AC power port instead of available/mutli-use-usb chargers;
*unit will overheat in direct sunlight unless AC is running, 90+F, don't bother;
*if delete all is used to wipe the card, it will corrupt the card in ways device can no longer write, it must be reformatted;
*the USB connection is USBv1.0 or v1.1... it maxes out at mere 400 kb per second and cannot server up files fast enough to review them on computer. Instead transfer the files to the computer and then watch, better yet pull the card and use a card reader for 30,000kb read speed and delete all without corrupting the card either!
*unit only records black with tiny lights in the distance at night, maybe a few glimpses of street paint lines

fact flash: IR frequencies are completely blocked by glass (not plastic, glass). I have no idea why this power wasting idea was put on something intended to sit behind a windshield that reflects it all back to the unit... only blank/blinded images are recorded in IR mode behind a windshield. However, leaving it on my work desk, or turning it around to watch the inside of the car in IR mode worked great for night patrol!

So far in 1 month I have used it to catch 1 office thief, 1 accident, and reported 3 people for major driving violations

Your device whore out after awhile, it utterly sucks and runs useless if you don't use it. What I mean is I didn't use it for awhile and it stopped working....What can I do, cause this happened to 2 of my elgato captures...... over 200 bucks wasted...

I haven't used it too extensively but for the use I bought it for it works great. I bought it to sync my Wii U pro controller to my computer and it does the job great (I did have to adjust some driver settings to get it to work however). But a nice surprise was being able to sync my Switch controllers up and use them a two controllers through the USB device.

What else would someone use this for? An old joystick? I doubt it. A OBD I scanner? Maybe. What would a regular home user use it for? I bet 90% want it for the old UPS the got sitting in the corner gathering dust with an obsolete serial port on the back. Guess what, I have an old UPS battery backup system with a serial connection. I wanted to use it on my new PC with Windows 7 64 bit. I installed the drivers on the mini CD that came with the converter. In fact, I installed BOTH drivers. One to activate and detect the USB device, and the other to activate and detect the "virtual" serial connection. When I got the "other devices" to turn into a serial port, I connected the converter to the UPS system and all it did was shut off. And that is all it does no matter what. After a little research, I found out that serial connections are not compatible with Windows 7. So, since this is advertised as "Windows 7 compatible" I am RMAing it and would rather get my money back (minus a few buck for shipping if they are too cheap to pay for it) rather than have a useless converter sitting in my drawer. I mean, what else am I going to use it for? Exactly.

...But don't rely on the "USB powered" feature - despite it having a double-headed USB cable allowing it to draw power from 2 USB ports at once, it is not 100% happy with just USB. It will certainly hang together long enough to do a backup, but if you leave it plugged in, after a few hours it will start to whinge about "Delayed write fail" as the system routinely ticks stuff off in the System Volume Information on the drive.

Also. the URL link supplied with the unit to download backup software is out of date - there is different, newer software to be had, but it is pretty fragile - it stops dead as soon as it hits a system file in Windows, for instance - plus it wants to sit in the background backing up everything you change all the time, which brings up the above mentioned "Delayed Write Fail" eventually.

In summary: If you are after a small, cheap drive which will back up your stuff, this thing works fine - but use your own backup software, and don't leave it plugged in 24/7 unless you have a handy 5V external PSU to hand (there is a socket for such a thing, indicating that even Iomega don't fully trust the USB power either).
