Logitech is Tried and True

I've owned different types of logitech products, that have stood the test of time and abuse, with the exception of their PS2 wireless controller, but that's another review.  I've bought this mic about over a year ago from writing, and I was amazed by some negative ones, and was grateful that mine hasn't acted as described.  This mic has seen many use from playing the Karaoke Revolution series and the Rockband series of games, for me it has worked flawlessly.  But then I have started to notice hearing static, and I noticed that when I switched it to a different USB port (USB1), the static goes away, which leads me to think that it might be the USB port of the PS2 which is the cause for many negative feedbacks.

Logitech

Works well with my HP laptop which has a touchy and sometimes non-responsive touch pad....Scroll wheel is a godsend....Only wish I had purchased earlier.......

Not too expensive and it loaded fast to both laptops I use them with. They have the dependable Logitech brand and I will never trust a different brand for mouse and keyboard ever again. Go Logitech! Typing is smooth and the mouse is quick and smooth. I am very happy with this pair.

The keyboard functions well and works for normal PCs (and I assume Macs). I purchased mine for a Raspberry Pi 2 running Rasbian and there seems to be issues with getting the Logitech unified driver to work with that device. Seems the driver support could be expanded a bit.

It's great!  Product met my expectations. Good ole Logitech - they usually make an excellent product. So, was not surprised that this purchased was perfect. Recommend this product.

I like the Logitech item . The only negative is the X-Y axis is a bit stiff.. otherwise, it is a good Flight Sim Controler...

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.

Logitech. Im sorry.
I knew better, but I got seduced by an off-brand bluetooth keyboard for my new Chromebox/tv set-up. Yes, it was pretty and low priced, but when I set-up the keyboard, it was slow and the touchpad crawled across the screen like a bug who was half asleep. Working with it for two nights didn't help. It was destined to be returned.

I already owned a Logitech K480 Bluetooth Keyboard, (designed by Batman, I think). It is responsive- a little heavy but the bluetooth response was grand! Grand I tell you!. Sadly it lacked a touchpad. I had to set my baby aside.

The Logitech K400 was the answer. Lightweight to hold with a highly responsive touchpad. I knew it had found a home in the first ten minutes of use. This unit is plug and play, you see. There is no sync with the Bluetooth signal as it used a dongle. I didn't have to worry about my wifi network interfering with my keyboards signal.

Logitech, I will never stray again.

Logitech is a reliable brand for wireless mouse. I have used several different brands of wireless mouse, in the beginning all of them works sleek- quick response and precise allocation in moving, clicking and swiping, but later some run out of battery in weeks, some lag moving or pressing, these malfunctions make using frustrated. But believe Logitech never let you down!

Good quality Logitech unit. Worked with no problems, installed automatically on Win 7, replacing another brand that was intermittent..

Logitech has become my preferred brand over the years based on ergonomics, performance, and value. I have been using a M305 model for the last couple of years with zero complaints. I recently needed another mouse but on a tight budget; have been very happy with the M325 so far at a fraction of the cost.

For a used item, it works just fine. Any issues I have I believe are from my unified remote not the switch. Need to get a better/newer Logitech remote.

I had one of these, and hubby had one by Microsoft. He seemed to be constantly changing his battery, whereas the Logitech lasts WAY longer (3-5 months in most cases) and I use my computer all day.

My in-laws wanted a normal keyboard and mouse, and since they have a laptop limiting the USB ports was important.

Great keyboard. For the price, it offers great tactile feedback.

It is *NOT* a "Unifying"  product. Neither keyboard nor mouse works with a Logitech Unifying receiver.

The Logitech mouse is much better than any other wireless mouse I've tried.  The Microsoft mouse is probably the worst.  I can count on the Logitech mouse to do whatever I want without complaint.  I like it so much, I got one for my husband.

Had problems with conflicting drivers, I have logitech mouse and logitech headphones. But once I figured out how to set them all up I am pleased with the keyboard. Again, kind of problem to set up, but a nice keyboard once you do. Like the screen.
