Great item!
works great. I can plug my backup into it and my printer, so I don't need to connect the printer to the internet.

Grub for a good price you wont be disappointed
**Works wonderfully with Apple devices** Plugged the hub into an M2 MacBook Air and everything was recognized instantly: the 4K @ 60 Hz HDMI output displayed crisp colors, the 100 W PD pass‑through kept the laptop charged at full speed, and the SD/TF slots read cards without any lag. The same seamless experience repeated on an iPad Pro 2024, proving the hub s broad Apple compatibility.
**Good flexible cables & build** The included 1 m USB‑C cable is surprisingly supple; it doesn t kink when you bend the hub around a laptop stand, and the strain‑relief sleeve prevents the connector from pulling out. The hub s aluminum body feels solid yet lightweight, and the rounded edges match Apple s design language, giving it a premium look that blends nicely on a desk.
**Ethernet port performance** The Gigabit Ethernet port delivers stable, low‑latency connections even when the hub is powering the laptop at 100 W. It s a reliable fallback for Wi‑Fi‑poor environments
**Overall impression** The Revodok 7‑in‑1 hub hits the sweet spot between functionality and aesthetics. It provides everything a Mac‑centric workflow needs high‑resolution HDMI, fast data ports, card readers, and robust Ethernet while looking like an extension of Apple s own product line. For anyone juggling multiple peripherals on a MacBook, iPad, or even a Steam Deck, it s a solid, hassle‑free solution.

Works perfectly aside from how hot it gets
The ability to add more ports to my different devices has been very helpful. I’ve tested it on my tablet, phone, desktop, and laptop and it’s worked exactly how I needed to. The only issue I’ve had with it is how hot it gets when using it especially when it’s using pass through charging. It will get noticeably hot when you touch it
