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.

NOKIA OF USB C HUBS
Color: Space grey
Howdy y’all, the only reason I’m doing a four star review is to keep it real.
The only annoying thing with the adapter when you plug it in kind of flops goes all over the place, but that is easily remedied by how useful it is. I’ve worked at Best Buy. I study software. I like my tech to be reliable and last, this adapter has not disappointed me the last almost 4 years now! It looks the same as pictured, maybe a couple scratches now but it has held up incredibly well. I initially got so I can connect my monitor and my mouse to my MacBook Pro and that continues to be my main use for it.
I’ve discovered it also works great at connecting to my iPad Air for extending the screen, mirroring, or using my mouse. It also works great for transferring data to other USB-C compatible devices like a Samsung phone! This thing has been reliable, I’ve used it to connect to external storage drives, SD cards, microSD cards. I keep finding new uses for it. It practically lives in my work bag all the time now. Also, I’ve only had it get somewhat warm like probably 2-3 times in my entire time of using it.
The reason I come back to review after all these years is my younger sibling asked if they could have my adapter and I’ve never felt so firmly in saying absolutely not. I’m grateful that you can still buy this because a lot of things I’ve purchased on Amazon haven’t lasted. When you find something good like this, especially in this day where things are built to break, you can’t help but appreciate the things that are reliable and consistent.
