Choosing computers peripherals can get confusing fast because the products here solve very different problems. One listing helps two computers share USB devices, another expands that idea with a USB 3.0 KVM-style switch, one is simply a 6-foot power cord extension, and one is a vintage mixed lot marked for parts or repair. The best choice is less about picking the most expensive item and more about matching the title, condition, and listed function to the job you actually need done.
Quick take
- Best for sharing USB devices between multiple computers: USB 2.0 Sharing Switch for Multiple Computers Peripherals LED Device Indicator, especially if the one-button switching and LED device indicators are the deciding features.
- Best for a two-computer, four-USB-device setup: USB 3.0 KVM Switch 2 In 4 Out 2 PCs Sharing 4 USB Peripherals for Desktop Laptop, because the title and description center on 2 PCs sharing 4 USB peripherals.
- Best for a basic cord need: Arista 6' Power Cord Extension for Computers and Peripherals - New Old Stock, the lowest listed price in this group.
- Best for vintage repair or parts projects: Lot Vtg Computer Mice Peripherals Serial PS/2 Trackball Wacom *PARTS/REPAIR, which is clearly framed around older mice, serial or PS/2 interfaces, a trackball, and Wacom-related hardware.
Listed price comparison
The listed prices run from USD 11.99 to USD 19.50, with the lowest-priced item 39% below the highest-priced item. The spread is modest, so the main decision should come from use case and condition rather than price alone.

Decision matrix
If your main problem is switching USB peripherals between computers: Start with the Sabrent USB 2.0 sharing switch. Its description calls out plug-and-play use, a single button for swapping systems, LED indicators, and USB data transfer speeds up to 480 Mbps.
If you want more USB outputs for two computers: The USB 3.0 KVM Switch 2 In 4 Out is the more targeted match. It is described as having 2 USB inputs and 4 USB outputs, with two computers sharing four USB devices.
If you only need a cord extension: The Arista 6' Power Cord Extension is the cleanest fit. It is not trying to switch, route, or manage peripherals; it is a cord extension for computers and peripherals.
If you collect, repair, or salvage older peripherals: The vintage lot is the only listing here built around serial, PS/2, trackball, Wacom, and parts/repair language. It is not a general everyday peripheral pick.
If condition is the deciding factor: The USB 3.0 KVM switch is marked new, the Arista cord is marked new other, the Sabrent switch is marked open box, and the vintage lot is explicitly parts/repair.
Concise product notes
USB 2.0 Sharing Switch for Multiple Computers Peripherals LED Device Indicator
This Sabrent switch is the most direct match for a shopper who wants multiple computers to share USB peripherals without moving cables back and forth. The title highlights USB 2.0 sharing, while the description adds a single button for changing systems, LED indicators to distinguish computers, and plug-and-play setup. The listed black color and universal compatible brand language make it feel aimed at a broad desk setup. Its main limitation is that it is a USB 2.0 device, so shoppers specifically seeking the USB 3.0 wording found elsewhere in this group should look at the KVM-style switch instead. It is also marked open box.
Lot Vtg Computer Mice Peripherals Serial PS/2 Trackball Wacom *PARTS/REPAIR
This lot is the specialist pick, not the practical everyday pick. The reason to choose it is right in the title and description: it brings together vintage computer mice and peripherals, including serial or PS/2 interface items, a trackball, and Wacom-related hardware. That makes it more relevant for someone working with older computer gear, parts bins, display projects, or repair experiments. The limitation is just as clear: it is marked *PARTS/REPAIR*, and the description says the items have defects or may not work at all. For a shopper who needs a working mouse or writing pad, this is the wrong direction.
Arista 6' Power Cord Extension for Computers and Peripherals - New Old Stock
The Arista 6-foot power cord extension is the simplest item in the group and also the lowest listed price. Choose it when the task is straightforward: adding a power cord extension for computers and peripherals. The title provides the key role, and the item is described as including one Arista 6' Power Cord Extension, with manufacturer part number 78-1131 appearing in the attributes. Its limitation is that it does not add ports, share devices, switch between computers, or solve USB routing needs. It is a cord accessory, so it should be compared only against other power-cord needs, not against the USB switches.
USB 3.0 KVM Switch 2 In 4 Out 2 PCs Sharing 4 USB Peripherals for Desktop Laptop
This is the better fit if your setup centers on two computers sharing several USB devices. The title specifies USB 3.0, 2 in 4 out, 2 PCs, and 4 USB peripherals, and the description mentions keyboard, mouse, USB printer, scanner, Bluetooth equipment, and other USB devices as examples. It also includes one-button swapping and two USB cables in the product description. The limitation is that its description says a 5V power supply port may be needed for higher-power devices such as HDDs or digital video cameras, and a power adapter is not included. It is more capable on paper than the basic USB 2.0 switch, but also more setup-specific.
Final recommendation
For most shoppers comparing these computers peripherals, the best first split is between USB sharing, power extension, and vintage parts.
If you need two computers to share common USB devices and want the lower-priced switching option, pick the USB 2.0 Sharing Switch for Multiple Computers Peripherals LED Device Indicator at USD 12.99. Its Sabrent name, black color, LED indicator wording, and USB-SW20 manufacturer part number make it the clearest basic USB-sharing choice in this set.
If your setup calls for two PCs sharing four USB peripherals, choose the USB 3.0 KVM Switch 2 In 4 Out 2 PCs Sharing 4 USB Peripherals for Desktop Laptop at USD 16.99. The concrete advantage is in the 2-in, 4-out USB layout and the USB 3.0 switch model wording.
If your need is simply a cord extension, the Arista 6' Power Cord Extension for Computers and Peripherals - New Old Stock at USD 11.99 is the practical pick because it is the lowest listed price and directly names the 6-foot cord role.
Only choose the **Lot Vtg Computer Mice Peripherals Serial PS/2 Trackball Wacom *PARTS/REPAIR at USD 19.50** if the parts/repair and vintage serial or PS/2 angle is the point of the purchase. It is the highest listed price here, and its own wording makes it a project lot rather than a ready everyday peripheral choice.
