| USB-C mechanical design is flimsy and pathetic. |

They are artists, what do you expect ? :palm: --- End quote --- There are plenty of micro USB connectors with TH. No issue with USB as such. The issue is with people who design their devices with non TH micro USB connectors in them. The same as when full size SMD (non TH) USB A/B connectors are used. |

Not everyone uses troughhole USB connectors yeah. But even the ones that are troughhole are often just tiny short pins that serve as alignment and don't actually stick out on the other side, seen those get ripped out too. As for MiniUSB reliability i had plenty of devices using it, Including smartphones that got plugged in daily for years (Early ones had terrible battery life.) and have yet to own a MiniUSB device or cable that started making intermittent connection. Maybe im just too gentle with my devices or they happened to have particularly high quality specimens. Sure the rated cycles in MiniUSB connectors are much lower than micro, but i have exceeded the rated cycles on mine and never noticed a problem. In any case given that the PCB can hold on to the connector id say a MiniUSB can handle at least twice or trice as much abusive force of repeated sideways tugging compared to MicroUSB before the connector fails. |

Most of the devices they are used in have something like 0.8mm PCB, not 1.6mm. Nonetheless, even if you use them on thicker PCB, they are way more robust than non TH connectors. Also you can get connectors with long mounting terminals if you need. |

I don't like the current trend of moving towards USB C only ports on laptops... I think usb A makes a lot more sense for many peripheral connections going forward, and not having any (or just 1) USB A is ridiculous..... But usb C also supports Thunderbolt channels, and, well, that's important nowdays so it's important that they have those too.. just not exclusively, please! For mobile devices I think usb C is great compared to USB micro b. Yeah I've had USB C cables go to crap, but never had an issue with device sockets so far... (Maybe because I've had them for less time? I don't know... ) But I hated the way USB micro B sockets would fail and need replacing... I had a couple of phones that I just decided to replace in the past, just from the USB micro b socket going unreliable... in both cases it took a phone that was oldish and a bit crap, but still useful, into something that was unusable... And then the decision to fix or replace is very hard to make when the phone is also old and maybe other things are going to be a problem soon anyway.... So in effect I've had USB micro b end the lives of a few devices earlier than they really should have ended. |

They are a limitation for laptop form factor. |
