I like ugreen and have never had issues with their products.
Especially their cables.

However I have had a few minor issues with drop outs, weird controller glitches and power management issues with this particular hub, over many months, on both a MacBook Pro 2018, and now an HP Omen Gaming Laptop 2019 (even while using a [not supplied] 5V 1A Micro-USB Power delivery [into the hub]).

It works OK for low power/light usage, but if you want better stable IO and better power management (ie, waking PC from connected USB child devices), and want to connect more complex devices requiring firmware updates (gaming equipment etc) you would be better off looking elsewhere. I suppose really, this fits it’s design, it’s light and portable, for light use, if you are at a desk more often, think of something bigger/mains powered/higher performance.

Anker and TP-Link make some good mains powered USB hubs, but they are less portable than this, so it’s a trade off.

Good luck! (try reviews, or your nearest computer street, stick to good brands at sensible prices, if you want stability).

PS. I have not got time to debug this properly or re-create it, the problems have occurred occasionally, but noticably, and importantly this is in comparison to my EXPERIENCE with 3+ other hubs, which never had these problems.

I will still buy ugreen products because I think they are a good manufacturer, no one is perfect.
