Perfect USB-C hub!
*If you are reading this and wondering if you should get it, or a competitor product that slightly lower in price... just get this one. You won't regret it.*
I already wrote a review, but I forgot to add photos. 1) I couldn't find a hub that had more than 2 USB-C ports; 2) This thing is tiny, doesn't demand attention, and built with aluminum. Not plastic, and doesn't feel cheap; 3) a life saver. I took velcro and mounted the little sucker under my MacBook mount. Now I could plug in my external drives, SD reader, and use the ports on my computer for other peripherals. One thing I was worried about was transfer speeds. I don't expect the fastest speeds ever, but I don't want to regret my purchase if it was going to give me more of a headache than a solution. To my surprise, the transfer speeds are fast, and feel faster than when they were plugged directly into my computer. One hard drive in particular always gave me trouble mounting. it would take forever. Since I purchased this drive it mounts in seconds.
I've used Satechi before, and their product have proven to me over and over to be reliable and of quality.

Works for me
This is plugged into a Macbook Air M2 and it supports a time machine drive, a 4TB solid state drive, a wired keyboard, and a free USB port for plugging various stuff into. In this use case, some other hubs don't work well with the Macbook; it keeps forgetting hub-linked drives are there, dropping them when asleep or not seeing them after a reboot. That has not been a problem with this hub. It's true I lose some of that Thunderbolt speed, but really, 5 GB/s is not that small a hole to put stuff through.

Leave the Laptop at Home - Content Backups
Style: Data Transfer (10Gbps)
I purchased this hub so I could leave the laptop at home and do backups of my GoPro Cameras and Drone footage to an SSD drive. I used FilePro Explorer app on my iPhone to set up tasks to do backups of my content from the SD cards to SSD drive. The one hiccup I encountered is FilePro Explorer (or this hub, not sure which) wouldn't recognize my GoPro cameras as a data source, so I had to remove the SD card from my GoPro Cameras, insert the card into another USB hub that had an SD card adapter (like the one here https://amzn.to/4dlkhMt ) and plug that into the Satechi Hub as another drive source, which it then recognized my SD card from the GoPro camera. So basically two small USB hubs and an App on my iPhone replaced what I would normally do with my laptop. Big weight savings when you're on a bike or motorcycle traveling.

Flaky and Fickle
Style: Data Transfer (10Gbps)
Worked great for a month. Went to plug in a spare ssd to back up files from tablet and it never has worked since. No data or power through any ports. The light turns on and stays solid but is just dead. Waste of my money for now it is outside of return and I am having troubles getting in touch with Satechi.

Love this thing
Style: Data Transfer (10Gbps), Style: Data Transfer (10Gbps)
I’m really impressed with my Satechi power passthrough 4 port USB C Hub.
It’s really slick, streamlined, and really good looking too.
It works well, doesn’t get hot or even warm to the touch.
