Excellent product! The ethernet connection actually gives the speed as advertised. Also, it comes with a USB 4 cable, which is nice. Many of the other products give a crappy USB with low speed. This is the 3rd one I bought that I did not have to return. Great product!

If you're looking for a thunderbolt 4 dock, you've likely come across brands like OWC, Satechi, Plugable, Kensington, and these specifically because you may have noticed that each of their thunderbolt 4 docks are in fact exactly the same. Same exact ports, specs, etc., in fact, they all use the same pcb so how is it that these companies can charge such an obscene mark up for a product that was not even of their own design or make? Why not just buy the least expensive one? That's what I did, and that turned out to be a mistake.In short, the one I received was a dud, had a horrible high pitched whine when it was plugged into power, and would get extremely hot, almost burning to the touch. However, considering other reviews expressing similar experiences to mine, my presumption I feel was wrong, this dud of a unit seemed more like the rule than outlier. I immediately returned it and ordered an OWC thunderbolt 4 dock. What I believed to be the same exact product with a different cosmetic appearance runs completely cool and does to my surprise have better quality parts, not to the extent that it is a unique product but at least enough such that the OWC distinguishes itself from the pack. (I'll leave my experience with satechi in its own review as that was an ordeal in itself and I likewise don't recommend their products.)Given my experience and those of others, I can not recommend this dock whatsoever. Whether the one you receive functions well is a coin toss, and even if it does, for how long will it last? The product inspires no confidence. You really do get what you pay for, and this ain't it.

Purchased this Kensington dock ("SD5700T Thunderbolt 4 Docking Station") to work with an M1 Pro 14" Macbook Pro. Main reason I chose it over others was the price - it was on sale for roughly 150, vs. the 220+ for other similar/identical devices.My particular unit does have a small amount of "coil whine" coming from the dock itself whenever it is powered on. (I'm in my early 40s but was a musician when younger and have protected my hearing more than most; some people may not notice the whine.) The edges of the aluminum have not been honed at all, they are not sharp enough to cut skin by running across it, but they are sharp enough that you can shave keratin off of a fingernail.The included Thunderbolt 4 cable is pretty short - not even a full meter long (I think it's listed at 0.8M). This may impact your desk arrangement, but it was tolerable for mine.Another oddity I have noticed is that in macOS at least, the audio jack does not appear until something is connected to it, and it disappears again after headphones or speakers have been unplugged. The SD Card slot behaves the same way -- the device itself does not even show up in the USB tree until you put a card into it. (I would normally expect to "see" an empty card reader device, but no.)The Thunderbolt ports behave as expected - I have two USB-C to DisplayPort adapters connected, each one driving a 4K display @60Hz. I am just using cheap AmazonBasics USB-C to DP1.4 dongles for this. (The displays themselves _do_ have USB-C inputs, but they also include downstream USB and Ethernet ports that I do not want to use, hence connecting via DP instead.) I have not tried to connect another Thunderbolt device downstream of the dock but I have no reason to believe it won't work.It's worth noting that this unit, the "Pluggable" dock with Amazon ID ("ASIN") B0CFC9CR5W, the OWC with ASIN B097TVLB4F, and probably a few others, all seem to use the same board layout and probably the same or very similar chips internally. The Pluggable version is notable in that it swaps one of the TB4 ports for an HDMI (seems like a downgrade to me), but then you also gain 2.5Gb Ethernet and the front port changes to USB3 (the front port on the Kensington is only USB2 / 480Mbps).The coil whine and the poor finishing of the enclosure give this dock a more cheap feeling than I was expecting, but for the price, it's hard to complain. Most other TB4 docks with the same port layout go for at least 70 USD more.

I recently purchased a new Macbook Pro with the intention of replacing my existing laptop and desktop, A majority of the this computer will be on my desk at my home office, but I wanted a clean setup that was easy to plug and unplug when I do take the laptop with me. My goal was to find a solid dock that could handle my various peripherals, multiple monitors, power my MBP, and do it all with only one cable connected to the MBP. So far, this dock has delivered perfectly!It's slim and attractive compared to some other options and reasonably priced to boot. As a sample case study, right now it is handling: one Apple Cinema Display (Mini DisplayPort to USC-C apadter), one Apple Cinema Display (Thunderbolt 2 to Thunderbolt 3 adapter), wireless USB keyboard, wireless USB mouse, Ethernet, and a lightning cable to charge my iPhone or iPad. All this while powering my MBP, allowing me to store the included charging brick in a drawer until I take it on the go.If you're looking for a similar setup, learn from my mistakes: skip an unpowered hub and make sure you get a Thunderbolt dock, not a USB-C dock. While they look the same, they're two very different things. There are other options out there depending on your port needs, but I'm confident this dock can work for most people.

Love this. Everything works great.
