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.
Where does this ship from?
Every unit we sell lives in one of two places before it gets to you. We tell you up-front so you can plan around it.

Either way, every device gets a 40-point inspection in our Mullingar workshop before it goes out, and carries the same 12-month warranty.
