What are you talking about?
Planned obsolescence, with the cheapest parts giving up the ghost first, so that the companies can make maximum short term profit on repairs with a flat rate, because they are required to make the maximum profit in the short term.
Paul Price had DS4000 fail few weeks before warranty expired, he contacted Rigol and then they said "No problem we'll fix it for free, it's in warranty. And please hurry up because you have only few weeks left."
And if he did that, he would be several weeks without a tool.
Do you have a car? If there is a problem with it, known to be covered under the manufacturers warranty (some sort of known defect), I assume you'll have it towed to the manufacturers designated mechanic on your own expense, and then wait for weeks for it to be fixed, and rent a car for your own use for the duration, and be happy with the warranty service? Right.
So Rigol have to give you better service than Keysight and than do it for free?
Huh?
Did you even read what I wrote?
No. I am not saying they should give better service. I am saying that even if they wanted to, it is difficult for them to do so, because this is how companies are required to operate nowadays. (I am not certain who exactly owns Rigol, and their Finnish sales seem good people, but unless a company is owned and run by people not focused on maximizing short term profits, they
cannot do better service.)
I have several pieces of Rigol equipment, and had problems only once in a few years. It was DP832, screen problem. I contacted reseller I bought it from and a the same time Rigol to ask who do I send it back to. Reseller got back to me for details, and sent me prepaid shipping slip. I sent PSU back next day, and day after that I received brand new one as replacement. It was sent before I send mine back..
In a week or so Rigol EU contacted me to check if all was sorted...
Excellent! And thanks for reporting a different, much better experience.
As to myself, I have had both good and bad warranty experiences. I'm not a Rigol or Keysight customer, so not with either of those; only with various computer parts and their manufacturers. The good experiences have been basically when the reseller replaced the item (soon after purchase, well within warranty); the bad when the manufacturer has taken a month or two to "fix" it (as far as I can tell, they all seem to have been replacements actually), and the worst when the manufacturer has taken two months to reply that the particular bit is not covered under the warranty -- which may be against the law here, as the entire product is covered under the warranty for at least manufacturing defects by law; but who has the energy to fight a company that claims that?
The nominally "bad" part has always been just having to do without the item in the mean time. If I had needed them for running a business, I would have just chucked the item, and bought a (better) replacement, from a different seller.
