Mechanical keyboards, switch colours and layouts:

the switch under each key decides how a mechanical keyboard feels and how loud it is. Red switches press smoothly with no bump, brown ones give a small bump just before the key registers, and blue ones click loudly enough to annoy anyone sharing the room. A membrane keyboard is quieter and cheaper again. Tenkeyless and compact boards drop the number pad to free space for the mouse, which suits gamers better than anyone typing figures all day. Then the layout. Keyboards sold as Spanish in Panama are usually the Latin American layout, not Spain’s with its Ç key, and the @ and the accents sit in different places on each.

Wireless mice and the receiver that pairs them:

a wireless mouse connects through a small USB receiver or over Bluetooth, and many Logitech models do both. The receiver is not universal: Logitech’s older Unifying receivers and the newer Logi Bolt ones cannot pair with each other’s devices, and the logo on the underside of the mouse shows which it needs. Vertical mice such as the MX Vertical hold the hand in a handshake grip. For calls, an external Full HD webcam beats most built-in laptop cameras, though a headset from headphones does more for how you sound than any webcam microphone.

USB-C hubs and docks for a thin laptop:

a hub is a small adapter that turns one port into a few, adding USB-A, HDMI or a card reader. A dock has its own power supply, charges the laptop through the same cable and drives screens from monitors. Neither shows a picture if the laptop’s USB-C port does not carry video, so look for the DisplayPort or Thunderbolt symbol beside it. A base MacBook Air from the M1 or M2 generation drives only one external screen on its own; a second needs a DisplayLink dock with its driver installed. Portable SSDs and external drives belong under storage and hard drives.

Xtech, Redragon and Logitech MX on the price ladder:

a wired keyboard and mouse set from a shelf brand such as Xtech, Klip Xtreme or Argom costs around $15 or less new in Panama, which leaves little reason to resell one. Logitech’s MX mice and keyboards sit around $100 to $140 new, with Redragon’s mechanical boards in between, and that upper end is where a used one pays off: switches, feet and battery are all easy to test at the handover, and a premium mouse that has lost its box but kept its receiver and cable gives up nothing in daily use.

Double clicks, chattering keys and fake Logitech mice:

switches wear, and on a mouse the first sign is a single press that registers as two, or a dragged file that drops halfway. Open a document and drag a block of text across it several times. On a keyboard the same wear shows as chatter, one press typing a letter twice, so type a full line on every row. A rechargeable mouse that no longer lasts the day has a battery near the end of its life. Copies of Logitech’s G and MX mice circulate in convincing boxes. A genuine one is recognised by Logitech’s own software, G Hub or Options+, and a fake usually is not; weight and the print on the receiver are the other giveaways. Try a dock on your own laptop and screen before paying for it.

Receiver, switch colour and power brick in the listing photos:

photograph the label underneath, which carries the model and the Unifying or Bolt logo, with the receiver beside it. State the switch colour and the layout. For a dock, say which laptops it has run, how many screens it drove and whether the power brick goes with it. Someone coming from Las Cumbres for a dock will bring their own laptop and expect a socket and a screen to test it on, and a keyboard buyer will want to type a line on every row first.
