Frequently Asked Questions
What does "refurbished" mean?
Refurbished means the item has been professionally inspected, tested, cleaned, and restored to full working order. Each device undergoes thorough diagnostics, data wiping, and any necessary repairs before being listed for sale. You get a fully functional product at a fraction of the new price.
What condition will my item be in?
Each product listing includes a detailed condition description covering the screen, case, keyboard/trackpad, and battery health. We use grades from Excellent to Fair - you can see our full grading guide here. Every item is unique, so please read the specific condition notes on each product page before purchasing.
What warranty do you offer?
Every product comes with a 12-month warranty covering technical defects and hardware failures. If your device develops a fault during the warranty period, we'll repair or replace it. The warranty does not cover accidental damage, liquid damage, or cosmetic wear.
What is your returns policy?
We offer a 14-day money-back guarantee. If you're not happy with your purchase for any reason, you can return it within 14 days of delivery for a full refund. Items must be returned in the same condition as received. See our full returns policy for details.
Has the data been wiped?
Yes, absolutely. Every device is securely data-wiped before resale. All personal data from previous owners is permanently erased, and the operating system is freshly installed. Your device arrives clean and ready to set up as your own.
What about battery health?
For laptops and tablets, we test and report the battery health on each product listing. You'll see a battery condition rating (e.g., "Good: 65-75% health") so you know exactly what to expect. Batteries are consumable components and naturally degrade over time, but all our devices hold a reasonable charge for daily use.
What's included in the box?
Each product includes the device itself and a compatible power supply/charger (unless stated otherwise in the listing). Original packaging is not included - items are securely packaged for safe delivery. Check individual listings for any additional accessories such as styluses, keyboards, or docking stations.
How long does delivery take?
Free tracked delivery is included with every order. Standard delivery takes 3-5 working days via DPD. You'll receive tracking information so you can follow your parcel every step of the way.
