Could not get the keyboard to connect to my Series 7 tablet. Installed, uninstalled and re-installed numerous times, but while the keyboard showed up on the Bluetooth list on the computer running Windows 7, it never recorded any keystrokes. Missed the return date, and now stuck with worthless piece of equipment. Ended up with a Logitech that plugs into the USB port and works fine.

Basically I plugged it in, installed drivers and it works.  It does what it is supposed to do and didn't cost a fortune.  Windows 7 32-bit

The usb end of it is misfabricated, so it won't just 'turn on' when inserted, you have to find the sweet spot or it will just sit there.  Other than that it's fine.

I found that the mouse, when it was working, worked fairly well. Nevertheless, I quickly became tired of the Razer Synapse software that popped up frequently requesting updates. Furthermore, I had intermittent connectivity issues. Every so often, I would boot up my computer to find that the mouse wouldn't work. The only fix I found was to plug the mouse into a different port to initiate driver installation, which would require a reboot to complete. The mouse would then work. While this may have been an issue with my computer, I can say that a Logitech mouse plugged into the same port immediately after I pulled the cable out worked flawlessly. I also have not had any of the same issues with the Logitech product.

Personally, I will not be buying any more Razer products. I found the software alone to be annoying enough to ditch the mouse.

I'm using the Plugable adapter to run a third display, as my PC's onboard display/graphics hardware only supports 2 displays.

First, the negative:  My Logitech mouse stopped working when I plugged the Plugable HDMI/DVI adapter next to the Logitech mouse dongle.  No matter what I did, the mouse refused to work.  I then unplugged the Logitech dongle and then plugged it in to a USB port in front of the computer and far away from the Plugable adapter that is plugged in in the back of my PC.  The Logitech mouse then works flawlessly.  It appears that the Logitech dongle does not like to be next to the Plugable adapter.

The good:  Plugable sent me an e-mail before I received the Plugable adapter.  The e-mail suggests that I download itss latest driver/software first.  Downloading and installing were easy.  I encountered no problem other than the mouse acting up mentioned above.  I can play youtube videos without a hitch on the monitor connected to the Plugable adapter.  Now I have 3 displays working with my PC.

My 1-year-old laptop lacked built-in Bluetooth (d'oh!) but this mouse works fine with a Zoom Bluetooth PC Card. I leave the card in the otherwise useless slot, and voila--no more fiddling with my dongle. HOWEVER--the CD supplied with the mouse contains Logitech's SetPoint software, which apparently only works with a keyboard/mouse combination. The program wouldn't even start up. I uninstalled it, and the mouse worked fine without it. All I needed to set up the connection was the utility for the Bluetooth card. I find that this mouse gives much smoother scrolling than the Microsoft wireless mouse I was using, which costs about the same and uses an annoying USB transceiver dongle that you have to remove and store under the mouse to turn the batteries off--after just a year, the mash-switch got wonky. But the V470 has a real, on-off switch and a push-button "connect" switch. No problem, no fumbling.

Fitting into USB 2.0 is annoying  but other than getting it connected, it works great.

I plugged my keyboard and mouse into this hub.  I had to plug them back into the computer, though, because they would stop working when plugged into this hub.  It works okay for charging things like my e-cigarette batteries and iphone.

Both the supplied USB cable and another I tried apparently do not connect well because a little bit of wiggle means that the computer loses the connection to the disk.

When I don't bump it, it seems to work fine although when I first plug it into the computer I now push the connector into the drive a little extra hard to make sure it works.

Used it to connect a mouse without USB plug worked just fine, the plug slides in easily without tightness or difficulty

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.

I bought this mouse for my wife, who had previously used the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Logitech-Optical-Notebook-Mouse-Plus-USB/dp/B0001LTT5K/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Logitech Optical Notebook Mouse Plus (USB)</a>&nbsp;and a basic Logitech optical mouse. The mouse fit her smaller hand well, and she has found the storable receiver very handy.

Worked perfectly. I already had the software, and I just plugged this in, followed the instructions, and it worked. Definitely recommend dealing straight with logitech - I've had issues with other supposedly logitech sellers and the receivers they've sent.

initially I couldn't get enough volume out of it but I switched USB ports and now it seems to work fine .. how strange.

Got a new laptop and lost a couple of USB ports in the process. Not a big deal when I'm on the road, only need a mouse and occasionally a thunb drive. But when I'm home, I add a keyboard and a backup drive. Since I have duplicate mouse and charger, one set stays on my desk, the other in my backpack. In the past, I pulled out the drive and keyboard USBs and dropped the Logitech receiver in a shot glass on my desk. But I thought that having a USB hub that would take all the stuff so I'd only have one thing to plug in when I got home would be great. Well, so close. drive and keyboard were recognized instantly. But I'm not able to get the mouse to work with Logitech through the receiver.

I was overjoyed when I plugged in the USB stick, turned on the keyboard, and it worked out of the box. It came out of the box with a pretty healthy battery charge and was able to use it immediately. No driver problems! :) I have a windows 7 and it worked fine. It seems like the mousing area would be better below the keyboard rather than above, but it's not too bad as it is.
