I've been using nothing but Logitech for years. I've had my mouse for 10 years, and it's still going great. Love my TKL keyboard, too. Agai, years without issues.
The only "gaming" peripherals I've ever had issues with are Razer products. Their quality fell off a cliff.
To digress slightly, I just killed my Logitech G19 keyboard, which I've been happy with for 10 years, so I immediately went out and treated myself to a G915 keyboard to replace it.
My first sign that something was awry was when I realised that a bunch of keys weren't working.
It wasn't just one or two. It was every 4th or 5th key.
Google for known issues and find you MUST install the Logitech software to get it to work reliably... which is fair enough, I guess, although it's slightly concerning that it means the keyboard can't reliably be used while installing an OS or twiddling with BIOS stuff.
I install the software and I find that all the keys which weren't working
are now working but, for those keys, there's no delay before they repeat.
So, for example, the "E" key previously wasn't working but now when I type a word like "when" I get "wheeeeen".
Great.
So, I google for known issues (again) and find
this is a common issue too and you need to go into the Windows keyboard settings and twiddle the delay and repeat sliders (something I've
never had to do before to get any keyboard working) to solve this problem.
Only trouble is, I
now find that, although the "iffy" keys are okay, I have to press all the other keys for
slightly longer before they register... which might not seem like a big deal but it makes touch-typing almost impossible.
Faff factor has reached critical mass.
Back in the box it goes, for a refund, and that's me done with Logitech keyboards, unfortunately.
Still got my G502 mouse, that I bought at the same time as my G19, and still perfectly happy with it but I'm afraid I won't be touching another Logitech keyboard.
Why would I buy a keyboard that
might have problems when there are so many alternatives out there that are, apparently, completely reliable?
Now the happy owner of an Asus ROG Strix Flare II Animate keyboard which is great... except for the name.
