I remember getting my first CalDigit TB dock and being excited - everyone seemed to love them. I expected it to largely Just Work.
That thing Didn't Work more than it Worked, but options were slim. Eventually it fully died about 14 months in. I didn't even bother checking to see what the warranty terms were. TS3 Plus, back in 17 or 18. What a piece of shit.
Sounds like it's a good thing I didn't bother trying again in the early 2020s and only recently bought a new dock.
I have a TS3+ that broke about 18 months in. I talked to support, set up a repair, and before I could send it the dock unbroke and had worked since. Truly mysterious and left me with a sense of unease with that thing given the cost.
Very similar story here. Went through two Caldigit TB hubs most recently a TB4. Soooo many issues. The same Ethernet issue described above, a failure to provide the rated PD power, and the TB linked monitor connection was dodgy af. A very expensive lesson. Add to this the confusing (and deceptive) jumble of TB cable standards. I have so many supposed TB3,4 and 5 rated cables I could probably circle my house. You have to hand Apple one thing and that’s the consistency of their hardware due to tight control of the stack and supply chain. You get far fewer of these sorts of issues.
