Plugable16-in-1 Thunderbolt 4 Dock – Dual 4K Monitors for M4 MacBook Air/Pro, 100W Charging, 2X HDMI, 2X DisplayPort, 2.5G Ethernet, 7X USB, MicroSD/SD Card Reader, Audio, Windows & USB4 Compatible

I bought this to dock a new gaming notebook to the two monitors, keyboard, mouse, speakers, mic, webcam, and other assorted odds and ends at my working desk. All of that is shared with a work notebook which has its own company-supplied "meh" quality off-brand Thunderbolt 3 dock, with both docks switching through a modern KVM so that I can jump back and forth as desired.As the new computer has a Thunderbolt 4 port, I wanted to go with a TB4 dock to allow for the possibility of higher resolution & higher refresh monitors and maybe even more of them at some point. This Plugable dock looked to be the best balance between price and features -- for the features, there just aren't that many docks at this price. A lot of the docks around this range don't even have DisplayPort, just capability for USB monitors. A lot of the ones at this price also tend to supply less power, which aren't enough for this computer. This one also seemed to make the top X on quite a few of the "best Thunderbolt 4 docks" lists.So nothing much to report in the functionality -- plug stuff in, stuff works. I had no issue with the computer locking onto the dock or the dock addressing any of the peripherals. Everything happens pretty much instantaneously. You get a nice green solid light to show successful TB connection with the computer, or white if no connection. The dock supplies 98W of power, which is enough to actively charge my power-hungry Lenovo Legion 5 Pro notebook which needs something close to that to charge while using. It's almost the 100W max for this computer for USB charging. Anyway, that certainly works.I had one hiccup -- toward the end of the first full day of use, it just stopped working at all, unable to ever establish a connection to any computer plugged into it. Swapped cable, same deal. I contacted tech support (after hours) via email and immediately got a human response acknowledging the problem, letting me know the real techs were going to be back in office first thing in the morning and would get with me, and as promised, they did, the very next day.Josh from Plugable, probably one of the most polite and pleasant people I've ever dealt with from a tech support team, was quick to ask for a bit more info, followed by acknowledgement that it appears that the dock is bad, and an offer to send out another immediately in exchange for promise of return from me using the shipping label that was to be included. Each interaction was very quick -- no long waits between emails. The package did arrive in just a couple of days and the replacement so far is working great. He mentioned really being eager to get that other one back with all of the original stuff (i.e., "please use only the new stuff [power supply, cable, etc] because we don't know which part of the old unit is the point of failure") so that they can diagnose the cause of the problem, presumably to know whether there are manufacturing or design issues to address. It's what I like to hear.Anyway, highly recommend this product. If you need it, the tech support is unbeatable. Hopefully you won't need it, and you'll have a really solid and frankly very attractive dock that looks good sitting on my desktop where my old mid-tower system used to be, along with easy access to USB ports and SD-card slots and a headphone jack.

Update: After enough troubleshooting on my own, I contacted Pluggable support. They responded quickly, had me try a few other things including running their diagnostic tool. Once they reviewed the diagnostics, they shipped me new dock and all of my troubles went away! Apparently the first one I received was defective. This dock works extremely well now with my 5K monitor, my other 1080p monitor, and all of my USB peripherals. Much happier with this dock and would certainly recommend it to others. If you do have an issue, don't hesitate to reach out to their tech support - they were great!I was excited to try this dock with my new laptop, but I keep being disappointed by it's functionality. It can't run my 5k monitor on either HDMI or displayport. It does run my 1080p monitor just fine though. I was using 2.5g network port on it for about the past month but noticed I was only getting about 1g of throughput. Switched to the 2.5g port in my laptop directly, and got 2.5g of throughput. I think this dock would be fine if you don't have big monitors, or monitors with high refresh rates - 60hz seems to be about all it can do. And if you are ok with 1g of network throughput you could be fine. If you are looking for more performance than that, you should look elsewhere. Very disappointed with this one especially for the high price.

Got this as a replacement for an HP thunderbolt 3 dock. It works wonderfully and is pretty sturdy with the included vertical base. It has two groups for displays, each with a DisplayPort and an HDMI connection. I ran into issues with running two monitors.My main monitor was using DisplayPort and was very stable, but my secondary monitor was running on HDMI and had loads of issues. Every time I would open a site like Crunchyroll or Spotify, the second monitor would go black and I'd have to reset my display settings in Windows to get it to work again. Also, running two monitors on Linux has been a tough time, but that might not be a dock issue.I've recently swapped to using a DisplayPort cable for my second monitor. Haven't tested with Linux, but on Windows all of my issues are fixed.TLDR: Excellent little dock with lots of features. Works great when using multiple monitors with the same type of connection, not so great with different connections. Great with Windows, YMMV when using Linux.
