I’d be stoked if a washing machine lasted a decade.

How so, not last a decade? I had AEG Lavamat 1055 about 35 years (from 1982), worked well without hitch. It was quite small, top loading model etc. Fast spin-dry w/ variomatic (shaking also while spinning). Laundry out of it was quite dry already. Then 2017 building plumbing had to be redone and gave reason to remake bathroom completely and replacing old equipment. I would have bought Miele model but it didn't fit re…

> How so, not last a decade?

Maybe it’s me then. We just don’t get that long out of them. We have tried Fisher and Paykel and Samsung. Never had more than and year warranty either.

They do run at least once a day often more, but that’s not enough to explain it.

Cars only show if they're well made after like a decade? These are not washing machines or something. Sadly that's also why it's hard to buy a new car, you only know what's a quality car years down the line. First impression matters though.

This would probably last a couple I expect

People talking about Chinese manufacturing all being junk are completely stuck in the past.

My grandfather in the 1970s used to complain about crappy Japanese tools. By the 1980s they were world-class. Same is happening with Chinese manufacturing.

My great-grandfather used to complain about crappy German tools.

My great-great-grandfather used to complain about crappy Scottish tools.

He was English. I am not sure you can buy as much as a paperclip made in England now.

Has to be said that nobody on this side of the pond ever complained about the quality of American Snap On tools though, just so long as the boss was paying for them.

> Vertical integration matters. If BYD controls much of the chain from the mine to the ship, they’re not paying everyone else’s margin along the way. That can translate into more car for the money. This is interesting. Wasn't the idea in Europe (and maybe elsewhere, too, no idea) that outsourcing components would lead to economies of scale? After all, a Mercedes or BMW or VW seat is still roughly a seat? It's interes…

VW, Mercedes and BMW also squeeze their suppliers very hard, and they operate with razor thin margins. So I agree and wouldn't say that doing everything in house is always going to be the cheaper way

Having an adversarial relationship with your suppliers is not necessarily the best arrangement. It means that suppliers will nickel-and-dime you for every change and ship minimum possible quality to you. The cost of loss of agility and quality will impact your bottom line.

In the last few years Chinese manufacturing has reached a very high-level. The reason most people still believe that Chinese-made stuff is poor quality is because they will do what they are told and they are usually told “make this as cheap as possible” by whoever is paying the bills. While I reckon some other countries still have specialist manufacturing in key areas that surpasses China, most “common” parts can be…

>they will do what they are told and they are usually told “make this as cheap as possible” by whoever is paying the bills It's more complicated than this. Historically, Chinese manufacturing has been notorious for quietly undermining the quality of the product to improve their margins over time, in a way that the commissioning brand doesn't notice. If a Chinese manufacturer quotes you a price too good to be true, th…

The most infamous example of this is hip implants made in China that had to be recalled due to being made wrong. This is also why Chinese structural steel is rarely used in North America and Europe.

>I have to say I'm super impressed with how heavy duty everything is.

But do you actually have a frame of reference though?

It's really easy to make stuff look good and then have it suck because someone in some other department nerfed it.

I'm not saying they're bad but HN is not a community I trust to make such assessments.

>The control arms, subframes, etc all look good and don't fit the 'chinese car bad' narrative you always hear. While I think the "chinese quality bad" narrative still applies to many Chinese brands, this isn't as universal as it was in the past. I think my eyes were first opened when I bought myself a Huawei phone(before the Google ban). My first few smartphones had been Samsung, I've always felt the term "planned ob…

Pre google ban huawei phones were incredible. 2-day batteries, great screens, fantastic cameras and an awesome price. I had a Samsung after my last huawei and it felt like a solid downgrade, even though the samsung was way more expensive.

FYI, if you are looking for a post google huawei, check out honor phones.

> manufacturers are just making gas cars with EV power trains. Tesla and BYD are making next gen transport. From what I see online, Teslas, especially MS/MX, are actually quite like an EV-swapped Toyota than anything futuristic. A lot about their cars(exception being CT and Semi) are ICE-mass-market-car coded. They're car equivalents of ARM PCs in ATX form factor like NVIDIA's DGX Station, opposite to the likes of tr…

MS/MX have been discontinued. Their basic design was ~ 20 years old (2007) I think model 3/y were more clean slate designs.

Yeah, so like, a PowerMac G5. But not like Mac Mini or iPhone.

I think it depends on the car. I've seen VW products fall apart in months after sale, we actually had a Mk5 golf that went back to the dealer three times in it's first year for fuel system faults. There are a lot of low price bracket Chinese imports (MGs mainly) that seem to have severe rust issues that are present at delivery. And Toyotas a few years ago had a problem where certain colour cars would have their paint…

A few years back my wife had a Toyota that had serious electrical problems (all instruments would stop working) that was eventually traced to a faulty sunroof combined with a terrible design...

> This prismatic cell is NOT a Blade, but it does share the same chemistry. Kind of surprised that the part that is perhaps the most "BYD" of the entire car, isn't actually the same cell that the BYD Blade batteries use, which was what I was most excited about seeing :(

I wonder if they simply couldn't fit it inside the scanner? From what I can find online, the biggest blade-cell dimension is 9.6cm, but I'm having a harder time finding the size limitations for the scanners.

> I wonder if they simply couldn't fit it inside the scanner?

As far as I know, the cells they use for the Blade does look more or less to what they actually scanned, I'm guessing it's the same size as the actual cell they used. Makes sense they couldn't fit the entire Blade assembly, as it's lots of cells put together, but I don't understand why they couldn't use the real thing instead of something else...
