This hubs got what I need and drives seem to mount right away.
Style: 5-in-1 USB-C Hub
Might be a little early to write this review. But, I feel like I keep buying these types of hubs and they never seem to have the right configuration for what I need. Two USB-Cs, Two USBs and an HDMI. Appreciate that the ports are all on the same side so I don't have a spider web of cables going in every direction. They all fit rather snugly. MOST IMPORTANTLY, every external drive and flash drive seems to mount right away.
I have had major frustrations over the years with external drives not mounting or taking forever to mount. I'm sure most of this is due to the failing drives themselves, but I have a sneaking suspicion the hubs are playing a role too, but I don't have the electrical engineering degree to prove it.
Anyway, so far so good with this one.

Work as expected
Style: 4-in-1 USB-C Hub
Work as expected. Plug and play. For a USB-C hub, worth the price. Had no compatibility issues with my PC and a laptop. Haven't noticed any heat issues.

Reliable, easy to use, and perfect for expanding ports on a MacBook
Color: Dark Red
This hub has been incredibly useful and very easy to use. I use it all the time with my MacBook and iPhone for transferring files, backing things up, and connecting multiple devices without constantly swapping cords around.
I really like the variety of ports included. Everything connects seamlessly and it has made working off my laptop so much more convenient. It’s compact enough to travel with but still gives you all the extra connections you need.
Definitely one of those accessories you don’t realize how much you need until you have it.

Works perfectly!
Color: Black, Color: Black
I was replacing my old one (Acer) because it would glitch out sometimes and not work how it should and I would have to mess with it to get it to work, I have an external keyboard, mouse and monitor for my MacBook Air and the dongle was perfect, I was able to plug everything in and it worked right away, with no problem!

Very good hub and great customer support.
Color: Space grey
I've been using this Hiearcool USB-C hub with my MacBook for work and daily use, and it does exactly what it promises. All the ports work well (HDMI, USB, SD card, and charging), and it's very convenient for office and travel. At one point, I had an issue under regular use and contacted their support. They were responsive and helpful, and they assisted me quickly with a solution, which I really appreciated. Overall, it's a solid hub for the price, reliable, and backed by good customer service. I'd definitely recommend it.
