When shopping for computers peripherals, the first decision is not simply "which one is best?" It is what problem you need to solve. A USB switch for sharing devices between computers is very different from a power cord extension, and both are far removed from a vintage parts/repair lot of mice, trackball, and Wacom-related peripherals. The right choice depends on whether you want daily desk convenience, a specific cable accessory, or older hardware for repair, collecting, or parts.
Quick take
- Best fit for sharing USB devices between two computers: The USB 3.0 KVM Switch 2 In 4 Out 2 PCs Sharing 4 USB Peripherals for Desktop Laptop is the most direct pick for a two-computer desk where keyboard, mouse, printer, scanner, or similar USB devices need to be shared.
- Best fit for sharing among more computers: The USB 2.0 Sharing Switch for 4 Computers & Peripherals, LED Indicators, Easy Setup is the clear match when the title's four-computer use case matters more than the lower USB version number.
- Best fit for a simple cord accessory: The Arista 6' Power Cord Extension for Computers and Peripherals - New Old Stock is the straightforward cable-focused option.
- Best fit for vintage parts work: The **Lot Vtg Computer Mice Peripherals Serial PS/2 Trackball Wacom *PARTS/REPAIR** is for shoppers who specifically want older mouse, trackball, serial, PS/2, or Wacom-related items in parts/repair condition.
Listed price comparison
The price spread is wide for this small set: the lowest listed item is 78% below the highest. That gap makes the use case especially important. A lower price does not mean a better buy if you need multi-computer USB sharing, and the highest price only makes sense if its four-computer switching role is the reason you are shopping.

Concise product notes
USB 3.0 KVM Switch 2 In 4 Out 2 PCs Sharing 4 USB Peripherals for Desktop Laptop
At USD 16.99, this is the most appealing desk-organization choice for someone who wants two computers to share several USB peripherals. The title calls out USB 3.0, two inputs, four outputs, desktops, and laptops, while the description points to one-button swapping and use with items such as a keyboard, mouse, USB printer, scanner, curve plotter, multifunction printer, and Bluetooth equipment. The package description includes a USB switcher and two USB cables. Its limitation is scope: it is built around two computers, so it is not the right match if the goal is to rotate devices across three or four computers.
USB 2.0 Sharing Switch for 4 Computers & Peripherals, LED Indicators, Easy Setup
This is the broadest computer-sharing option in the group, and its USD 53.35 listed price reflects that it targets a larger setup than the two-computer USB switch. The title emphasizes four computers and peripherals, while the features include 4-way operation, USB 2.0 compliance, manual control, plug-in connectors, and LED indicators. It is the option to focus on if seeing which computer is selected matters, or if four-computer access is the central requirement. The tradeoff is that it is USB 2.0, and it sits at the top of this comparison's listed price range rather than near the lower end.
Arista 6' Power Cord Extension for Computers and Peripherals - New Old Stock
The Arista cord is the simplest product here: a 6-foot power cord extension for computers and peripherals, listed at USD 11.99. It is also the lowest-priced item in the set, with Arista named in the title and attributes, plus manufacturer part number 78-1131. Choose it when the shopping need is specifically extending a power cord rather than connecting, switching, or sharing USB devices. The limitation is just as clear: it is not a hub, KVM switch, mouse, or adapter for data peripherals. If the problem is multiple computers sharing printers, keyboards, or other USB devices, one of the switching products fits better.
Lot Vtg Computer Mice Peripherals Serial PS/2 Trackball Wacom *PARTS/REPAIR
The vintage lot is the most specialized choice. At USD 19.50, it is for a shopper who is intentionally looking for older computer mice and related peripherals, including serial or PS/2 interface items, a trackball reference, and Wacom in the title. The reason to choose it is the mix: it can make sense for parts projects, repair attempts, retro-computing interest, or collecting older input hardware. The limitation is central to the title and description: *PARTS/REPAIR* is not a casual condition detail. It should not be treated like a normal ready-to-use mouse purchase for a current desktop setup.
Final recommendation
For most shoppers looking at computers peripherals for an active desk setup, start with the USB 3.0 KVM Switch 2 In 4 Out 2 PCs Sharing 4 USB Peripherals for Desktop Laptop if the goal is two computers sharing USB devices. Its two-input, four-output design and one-button swapping make the use case easy to understand.
If the desk has more computers in play, the USB 2.0 Sharing Switch for 4 Computers & Peripherals, LED Indicators, Easy Setup is the better functional match because its title and features center on four-computer sharing, LED indicators, and manual control. The price spread in this group is significant, so choose it for the four-computer requirement rather than simply as a general USB accessory.
Pick the Arista 6' Power Cord Extension for Computers and Peripherals - New Old Stock only when the need is a 6-foot power extension. Pick the **Lot Vtg Computer Mice Peripherals Serial PS/2 Trackball Wacom *PARTS/REPAIR** only when the vintage, serial, PS/2, and parts/repair nature is the point of the purchase.
