If a single switch goes bad after 15 years of constant usage, I wouldn't feel so bad, to be honest. Considering the worst membrane keyboard I have is going strong after 10 years (which is a Microsoft keyboard), I believe this G710+ can last much more than that.

We have 20+ year old keyboards at office which are going strong and some are even connected via DIN to USB adapters.

So a good mechanical switch like a Cherry MX cannot be killed in a reasonable amount of time even if you use it daily without abusing it, if there's no defect in production.

I didn't change a Logitech peripheral due to malfunction until now. Some of these are used daily, non stop.

So, I'm not expecting this G710+ to apply for retirement soon.

Wait, is my i key not registering? Nope, just joking. :)

I’ve been using mechanical keyboards for at least a decade now and the only time I’ve had a switch go bad was when I spilled a drink on it. Technically it was still good but since it was a sugary drink the switch got sticky.

As many before me have said, I am a professional programmer. I don’t care nor have the time to replace switches. I have a backup keyboard that gets swapped in if a switch goes out. I’m never going to tear a board apart to replace a switch.

I spilled half a pint of beer into my kinesis advantage (cherry brown switches) and it worked fine after opening it and giving it a wipe down and letting it dry. Switches failing just isn't on my radar. I'd be more worried about the extra failure mode of the sockets needed for swappable switches. If it comes down to it I can solder in a new switch.
