So far, so good. It's a USB-C hub, Anker has been doing USB hubs and power supplies for many years
I've always been impressed with Anker products, and great customer service! I do feel like they are starting to abandon the Android side of things recently, and the selection of cables has declined. USB-A cables seem to be discontinued, as well as USB-B. I did have a really great CSR experience a while back. I had bought a Lithium Ion car battery jumpstarters, and had not used it for several years. I needed it one night, and the cables to connect to the battery had failed. Couldn't start my car. Even though the warranty was expired, and the product was even discontinued, they shipped me (at their cost) a replacement set of cables. Now a loyal customer.

good on 16-inch MacBookPro and ThinkPad but not 13-inch MacBookPro; intermittent USB 3.2 connections
UPDATE 2025-NOV - lowering to 3-stars: Found that only the 2nd USB-C from the right is truly USB 3.2 compliant. Using the same SSD and same USB-C 3.2 cable, only the 2nd port from the right connects at 10Gbps speeds for RTL9210B-chipset enclosure SSDs (and I have tested with 4 different ones). The other 2 ports on this Anker adapter are intermittent, sometimes they connect the SSD as USB 3.0 and sometimes it connects as USB 2.0, for the same SSDs. The odd thing (as possible workaround) is that if we use a USB-C to USB-A female adapter and then use a USB-A to USB-C cable to the same SSD, it now connects at USB 3.0 speed on any of the ports, but transfers only at 5Gbps throughput. Another annoying thing is, this Anker adapter, even after the firmware upgrade, still intermittently "sleeps" or "goes offline" and disconnects from the laptop (does this on both my MacBook and ThinkPad). It does automatically reconnect after a few seconds, but very annoying, and can possibly corrupt drives that are connected when it happens. ORIGINAL REVIEW - 4 stars: USB-C hub is fast, able to transfer 5+ Gbps to SSD. Video display quality is OK for 1440p (when it works). DisplayPort video worked on ThinkPad and 16-inch MacBookPro, but not on 13-inch MacBookPro; connecting to a USB-C connected monitor (video worked without this Anker adapter). USB-C cable length to host computer is long enough. Worth the $30 price I paid ... yes; it served the purpose of having a USB-C hub while still being able to use the USB-C port for DisplayPort video; overall good design.

Video output does not contain power — caveats and findings for Switch users to whom this may concern
The product works with some caveats, which I initially tried to resolve with an ultimately unsuccessful firmware upgrade. (Anker was responsive via email, much appreciated.) It turns out the product was working to the best of its abilities this whole time, which I will now expound upon. I expect that perhaps another 4-5 people in the world intended to use this in the ways that I did, namely with a Nintendo Switch as the source to various output devices. If you are one of these people who are interested in reading my experience connecting this hub with a Nintendo Switch, my findings are below (after a brief primer). A Brief Primer 1. As you know, the Nintendo Switch can be coaxed to output Dp-Alt video if you can satisify a 39W+ handshake (15V, 2.6A or higher) 2. There are other adapters that will do this and output the video (with ample power) over USB-C, which are useful for powering AR glasses, portable monitors, or desktop USB-C monitors. 3. The limitation of a USB-C Dp-Alt adapter is that it does not also provide USB data ports like the Switch Dock itself, while many USB-C to HDMI dongles include USB-A ports. (But we don't want HDMI out, of course, because using USB-C we can power AR glasses or a portable monitor and send the video signal with one cable.) 4. I surmised that, by chaining a USB-C Dp Alt Adapter to this one (Anker A8340), I could have video output and three USB-C ports. Why do I want USB-C data ports? Since you are like me, you already know it is so I can connect a UAC1 DAC to output USB Audio and power thirsty headphones via a 4.4mm Pentacon balanced headphone jack. I also don't need to convince you of the merits of this versus using the Switch's built in 3.5mm headphone jack. Or say, connecting a wired controller because I don't care for input latency if I can avoid it. My Findings 1. This hub can indeed be chained to a USB-C Dp-Alt adapter and pass through a video signal while also leaving three USB 3.2 data ports for wired devices (yes!) 2. However, as other reviews kindly mention, the video signal outputted by the A8340 does not contain power of any sort. So, if you are intending to plug this into a desktop USB-C monitor which already has/doesn't need power, then everything is awesome. 3. If you are trying to power AR glasses, this won't work unless you add a second USB-C DP-Alt adapter after it, and provide power that way. If you intend to convert the video signal to HDMI or DisplayPort via a USB-C to HDMI or DP cable, these won't work because there is no power for the inline conversion. 4. If you are using a USB-C travel monitor, this will work provided you directly power the monitor via its second USB-C power (if it has one). So in summation, it's possible to get what you want, though you may find the victory pyrrhic. The perfect adapter (which I had hope this was, and may yet exist at a higher price point) basically takes a USB-C Dp-Alt adapter, adds USB-C data ports, and outputs USB-C + power to power AR glasses or a travel monitor. This device nevertheless has its uses, such as the ability to connect multiple USB-C devices to the Switch in handheld mode and charge it, too.

Simple and reliable. No Flaws.
Flawless performance so far. I use this item with my iMac, and I'm able to run a 12 channel music interface through it with no noticeable lag.
