Grading & condition explained
Every device we sell goes through a 40-point inspection by our in-house team in Mullingar. Worn batteries replaced, scratched screens renewed, faulty buttons fixed. Battery, display, camera, ports and speakers all tested.
Then we grade purely on cosmetics. Performance is identical across grades — the difference is how the device looks, not how it works. Every grade carries the same 12-month warranty.
- New
- Brand new in sealed packaging. Never used. Full original accessories and warranty.
- Grade A+ — Pristine
- Looks and feels new. Includes never-used returns, ex-demo units (briefly used in a shop), and factory-refurbished stock from the manufacturer. Indistinguishable from new in everyday use.
- Grade A — Excellent
- Refurbished and fully tested. Possible minor cosmetic marks, only noticeable on close inspection under bright light. Our most common grade and the best balance of price and condition.
- Grade B — Good
- Visible signs of use — scratches, nicks or wear on the casing. Cosmetic only, fully functional, biggest discount on refurbished stock.
- Grade C — Fair
- Heavy signs of use. Cosmetic only, fully functional. Our lowest price when available — ideal if budget matters more than appearance.
We’re straight with you on grading. If something’s a Grade B, we call it Grade B — we don’t soften the language. The grade is on every product page and the photos show the actual stock condition.
Keyboard layouts explained
Refurbished laptops come from different source markets, so the keyboard layout varies. The keys are the same physical shape; the position of punctuation and currency symbols differs. For Ireland, you want English UK (also called Irish on some units).
- English UK / Irish — the Ireland default
- £ on Shift+3, @ next to the Enter key, # on Shift+3 (alt). What you grew up using. Most refurbished laptops sourced from the UK and Ireland.
- English US
- No £ key — $ takes its place. @ moves to Shift+2. Different Enter key shape (horizontal vs L-shaped). Will type English fine; takes a few days to adjust if you’re used to UK.
- German (QWERTZ)
- Z and Y are swapped, ß on its own key, special characters in different spots. Will type English fine but the muscle memory is genuinely different.
- French / Belgian (AZERTY)
- A and Q swapped, Z and W swapped, numbers require Shift to type. Different enough that we don’t recommend unless you specifically want it.
- Nordic (SE / FI / NO / DK)
- QWERTY base with å, ä, ö on their own keys to the right of L. Otherwise close to English UK in feel. Easy to adjust to.
- Other European (Dutch, Swiss, Spanish, Italian…)
- QWERTY-based with local accent and punctuation positions. Generally fine for English typing.
Use the Keyboard Language filter in the category sidebar to narrow to the layout you want, or chat to us on WhatsApp if you need a specific layout we don’t currently have in stock.
Where does this ship from?

Store collection: 2–3 working days (we’ll text you the moment it’s ready in Mullingar).
Either way, every device gets a 40-point inspection in our Mullingar workshop before it goes out, and carries the same 12-month warranty.
