Our take
Choose ULDPLS-SGR when you need a broad USB-C dock with HDMI and Mini DisplayPort, Gigabit Ethernet, card readers, and USB-C data/power. Its best display fit is one 4K30 screen or, on supported Windows systems, two 1080p screens; Mac is limited to one external display.
A USB-C laptop user who needs wired networking, card readers, and display flexibility, particularly a Windows setup that can use two 1080p screens..
It is not the right fit for 4K60, more USB-A ports, Mac dual-screen use, or a verified direct offer for historical ASIN B07PS17X63.

Full review: how the features affect your choice
What the features mean for you
Bring display, network, storage, and USB together
ULDPLS-SGR is a multiport USB-C dock that combines HDMI, Mini DisplayPort, two USB-A ports, a USB-C port, Gigabit Ethernet, and SD/microSD reading. It can attach wired networking and memory cards alongside a display and USB peripherals. ALOGIC describes the USB-C output as supporting both data and power, which separates it from a PD-only input. Confirm that the current unit's port arrangement matches the official SKU before buying, especially if the USB-C port's data function matters.
Choose between one 4K screen and two 1080p screens
ALOGIC lists up to 4K30 through either HDMI or Mini DisplayPort when used singly. It also documents two 1080p displays together on Windows 10 or later when HDMI and Mini DisplayPort are both connected; the page limits Mac computers to one external monitor. That platform difference is central to the choice. Check the computer's video-output capability and the exact mode you need rather than relying on a broad dual-display label.
Check the network, USB, and card-reader needs
The two USB-A ports are specified as USB 3.1 Gen 1, while ALOGIC describes data support through the USB-A and USB-C ports. RJ45 supports 10/100/1000 Ethernet, and the hub includes separate SD and microSD slots. The inspected page does not state reader speed or whether both card slots work simultaneously. If your workflow depends on a particular card standard or transfer behavior, check the full current manual instead of assuming every interface operates at its maximum while other ports are active.
Plan laptop charging and USB-C data together
ALOGIC says the USB-C port supports both data and up to 100W Power Delivery when connected to a suitable charger. The listed 100W is a maximum advertised capability; the inspected page does not state laptop-side output under every combination of attached devices. The product description identifies both data and charging roles on that port, so it can serve a USB-C peripheral and a charging path. Check the laptop requirement, charger, and current device support before depending on full-rate charging.
Keep ULDPLS-SGR distinct from Dock PLUS Gen 2
The ALOGIC page identifies ULDPLS-SGR, an older Dock PLUS version with HDMI and Mini DisplayPort up to 4K30. It is not ULDPLSV2-SGR Dock PLUS Gen 2, whose official page describes different display modes and dual-4K capability. The historical row remains tied to the first model. ALOGIC's sources do not verify B07PS17X63 as a current offer, so use the tagged model search and check the SKU and display mode before choosing a result.
