Great docking station! I use this for my Steam Deck and it works perfectly to connect to the TV. The 4K video is high quality and the ethernet port makes downloading games so much faster than wifi. It is compact and takes up very little space on my desk. very easy to set up and use with all my accessories. Amazing value for the price. I would highly recommend it to anyone who wants to play on a bigger screen.

This dock worked great with my 1TB OLED Steam Deck. It was easy to set up and the picture quality is great. I am able to charge the Steam Deck while casting the image on to my TV screen. Good price and good product.

It's great! I was hoping to connect my steam deck because the battery dies kind of fast, and it's a very heavy console so my wrists hurt after about an hour of using it, but with this docking station I can just plug it and continue playing without worrying about the battery life nor my wrist pain. It really is a life-saver. I was also having issues connecting my controllers to the steam deck itself, but with the docking station I can just plug them in without the need of Bluetooth connection. There's absolutely no issues with the docking station itself: it came in perfect condition, it runs games perfectly on my TV, and it doesn't cause any damage on the steamdeck, just in caee anyone was scared that it might damage it somehow. But keep in mind that you might have to switch the graphics (the resolution) manually when you switch from using it on your TV vs the deck itself. It doesn't happen always, and it's easily fixed in like two seconds, but I was a bit taken aback when I noticed the image quality at first. Overall, I wish I had purchased this sooner since it would've saved me a lot of trouble!

Excellent addition to my living room set up. Simple to use just plug and play, light weight and my steam deck fit perfectly on it. Sturdy with a nice feel to it. Charges fast, and the cable is long enough to reach divices from both sides and top.

I’ve been using this dock with my Steam Deck and it’s been great so far. Setup was plug-and-play and it outputs to my TV without any issues. The Deck sits securely in the dock and all the ports work as expected for charging, HDMI, and accessories. I was also pleasantly surprised that it works with my Switch 2 as well, which makes it even more useful. Video output is stable and there’s no connection fiddling required. Overall, it feels well-built, does exactly what I need, and costs a lot less than the official options. Definitely happy with the purchase.
