When shopping for computers peripherals, the first decision is not which item looks best; it is what problem you are trying to solve. A mouse, keyboard, power cord, and USB sharing switch do very different jobs, so the right pick depends on whether you are restoring an older setup, improving typing layout, powering a device, or sharing one USB peripheral across multiple computers.
Quick take
- Best for a retro PS/2 setup: Packard Bell Musbjl Mouse PS/2 Connections Port Retro Vintage 160125 Untested, because it is a Packard Bell M-S34 mouse with PS/2 connectivity.
- Best for an ergonomic typing layout: Microsoft natural ergonomic keyboard used condition 4000 v1.0 tested works, because it is listed as an ergonomic Microsoft keyboard.
- Best for a simple replacement-style power cable: Radioshack 6ft AC Power Cord 125VAC Computers Peripherals Calculators 2781262A, because it is a new 6ft cord with standard 3 prong connectors on both ends.
- Best for sharing one USB device: 4 Computers To 1 USB Device Sharing Selector Switch, because it is described for sharing one USB 2.0 device among four computers.
Listed price comparison
The set runs from USD 15.00 to USD 24.99, with the lowest listed price 40% below the highest. That spread is narrow enough that the better choice is mostly about function rather than chasing a single cheapest item.

Concise product notes
Packard Bell Musbjl Mouse PS/2 Connections Port Retro Vintage 160125 Untested
This Packard Bell mouse is the most specific fit for someone working with a retro or older computer setup that uses PS/2. The M-S34 model reference and Mouse PS/2 type make its role clear: it is a pointing device for a PS/2 connection rather than a general modern USB accessory. The retro Packard Bell styling may also matter if you are trying to keep a period-correct desktop look. The main limitation is right in the title: it is marked untested. It is also a used item, and the PS/2 connection narrows its fit to systems that can use that port.
Microsoft natural ergonomic keyboard used condition 4000 v1.0 tested works
The Microsoft Natural Ergonomic Keyboard 4000 v1.0 is the pick here when the goal is a keyboard rather than a cable, mouse, or switch. Its strongest reason to choose it is the ergonomic type, which points to a keyboard layout intended for a different hand position than a standard straight keyboard. The title also includes tested works, which is a concrete phrase shoppers may value when comparing used peripherals. Its limitation is that it is still a used-condition keyboard and it sits at the top of this group's listed price range, so it makes the most sense when the ergonomic keyboard role is the priority.
Radioshack 6ft AC Power Cord 125VAC Computers Peripherals Calculators 2781262A
The RadioShack 6ft AC Power Cord is the straightforward utility item in this set. Choose it if the job is connecting compatible computers peripherals or calculators using a standard 3 prong power cord arrangement. The 6ft length gives it a clear use case where a short cord would be less convenient, and both connector ends are described as standard 3 prong power cord connectors. Its limitation is equally clear: it is not an input device and not a sharing hub. If your problem is typing, pointing, or switching a USB device between computers, this cord will not address that category of need.
4 Computers To 1 USB Device Sharing Selector Switch
The 4 Computers To 1 USB Device Sharing Selector Switch is the most flexible pick for a shared-peripheral desk. It is described as a 4-port USB 2.0 sharing switch that can let four computers share one USB device, with examples such as a printer, scanner, storage device, webcam, keyboard, mouse, or card reader. The push-button selection idea also keeps the purpose easy to understand. The limitation is that it is a switch box, not the peripheral itself. It helps route access to a USB device, but it does not replace a keyboard, mouse, power cord, printer, or scanner on its own.
How to choose among them
Start with the connection or task. If the computer has a PS/2 port and needs a mouse, the Packard Bell PS/2 mouse is the only item here aimed at that situation. If the desk needs a keyboard and the ergonomic layout is the appeal, the Microsoft Natural Ergonomic Keyboard 4000 v1.0 is the focused match. If the missing piece is simply a standard 3 prong AC cord, the RadioShack cord is the cleanest choice because the title and attributes center on power connection rather than control or data switching.
The USB sharing selector is different from the other three because it is an organizer for a multi-computer setup. It is the logical choice when one USB device needs to be shared among several computers, especially if the device is already on hand. It is less useful if you need a standalone peripheral immediately, because it depends on another USB device being part of the setup.
Condition is also a useful divider. The RadioShack cord and USB sharing selector are listed as new. The Packard Bell mouse and Microsoft keyboard are listed as used, with the Packard Bell title also saying untested and the Microsoft title saying tested works. For a shopper choosing between the two used input devices, that wording may be just as important as the product type.
Final recommendation
For most shoppers, choose by purpose first. The 4 Computers To 1 USB Device Sharing Selector Switch is the most broadly useful desk-management item at USD 15.00, especially because it is the lowest listed price and is meant for sharing one USB device across four computers. Pick the Radioshack 6ft AC Power Cord 125VAC Computers Peripherals Calculators 2781262A at USD 17.50 when the need is specifically a new 6ft standard 3 prong cord. Choose the Packard Bell Musbjl Mouse PS/2 Connections Port Retro Vintage 160125 Untested at USD 19.87 only when PS/2 and vintage Packard Bell fit the setup. Go with the Microsoft natural ergonomic keyboard used condition 4000 v1.0 tested works at USD 24.99 when the ergonomic keyboard role outweighs the fact that it is the highest listed price in this comparison.
