It's up to you choosing your buying source We are one of the first EU sellers receiving the fixed version directly from the factory. Our current serial number range is SDS1EBBD1Rxxx.
Nevertheless the real problem is: Manufacturer sells a defective product with an alleged three year warranty. Product has a design/manufacturing error.
A serious manufacturer would:
1) Issue a recall, so that units still in the dealers' inventory are frozen and replaced so that no more defective units are sold.
2) Organize a recall process so that units in the hands of customers can be replaced/fixed.
Some will dispute wether this is a design/manufacturing error or not.
I'd like to see quotes of the user manual of any oscilloscope suggesting that probe calibration must be repeated for every vertical range.
Of course I know it's largely a cosmetic issue that won't render the scope useless. But it's still a reputational problem whenever someone notices the problem and learns that the manufacturer didn't honor the warranty.
There are two kinds of manufacturers: Those who honor the warranty strictly in legal terms and only when it's not possible to avoid it, and those who understand that being more proactive can be good for their reputation.
20 years ago, for example, I had a good experience with Sony, who fixed a walkman way out of warranty for free. They opened it and it was obvious it was a defect, not user damage. They said that no matter what the warranty said, it was obviously their fault. They apologised and fixed it for free.
Law and ethics are not always coincident. And even from a purely selfish point of view, reputation is important. As someone else pointed out, a good reputation can take years to earn, and it can be lost in a second.
