--- Quote from: ebastler on February 17, 2023, 06:24:45 am ---I don't recall seeing any repair threads on this forum where users had to fix a broken Hantek, Owon, Siglent, or Rigol scope. Firmware hacking, modifications (e.g. encoder upgrades, quiet fans), sure -- but no repairs needed, it seems. --- End quote --- That is due to the fact that they mostly ask these questions in the hacking threads instead of starting new ones :) At least I have seen this happen for the FNIRSI scopes, but these are the bottom of the barrel ones. |

--- Quote from: H713 on February 17, 2023, 06:24:35 am --- The scopes coming from the far east seem to be fine. Are they as reliable as a Keysight or a Tek? Of course not, but that's what you get for $500. As a guess, I'd expect 10 years of hobby use, or maybe 5 years of constant lab use. Odds are the fault will be an encoder, PSU or display issue, and if you're so inclined, any of these is likely to be pretty fixable even without schematics. --- End quote --- Odds are that, today, it will be more likely that big brand products will have problems and even built in planned obsolescence. There are many threads from people repairing Keysight scope PSUs, FLASH data roth in Megazoom scopes etc.. Lecroy suitcase scopes had pretty bad reliability at one point... Many big brands scopes had bad reliability, but that is usually forgotten because companies usually have maintenance contracts and it gets shrugged off as all is well that ends well... And, funny enough, simple devices are going to be more reliable. And also: Far East? Does that include Japan, that designed and made most reliable devices for HP in legendary days? My brother had bad experience with his Peugeot.. All of them European cars are shit... Is that the reasoning..? Truth is, China, for example, has better functioning space program than the rest of the world combined. And many other examples of premium quality industries. But it is a country that is larger in population than USA and EU combined. They have some manufacturers that established world class product lines and some small local companies that make cheap, questionable stuff that is just cringy. Like any other country. Generalization is not wrong here because it is not PC. It is simply factually wrong and not applicable. Example of Chinese origin manufacturers that make good products and are global players are Siglent and Rigol. They both have global presence, HQ and support on all continents etc. They are real T&M manufacturers. They are world companies in truest sense. If you buy something like Finrsi that comes from some unknown company from somewhere, it is not fact that it is from China that defines the quality. It is the manufacturer that is what it is. |

Price/brand is no indicator of reliability, eg. Mercedes Benz make some of the least reliable cars. |

People try and find cheapest shit from China and then complain about quality and say everything Chinese is bad.. It is about good or bad brands. Not countries. Xiaomi phone I have is superb. Next one will be also be Xiaomi.. I couldn't care less if it is Chinese or not... |
