Frequently Asked Questions

What warranty do refurbished products have?

We offer warranties tailored to the type of customer and product:

🏢 B2B Clients (companies and professionals)

Standard 12-month warranty for servers, components, and IT equipment, extendable according to customer needs.
Lifetime warranty for networking equipment from Cisco, Arista, Juniper, and Arpers transceivers.
6-month warranty for batteries and power supplies.
IP Phones: 12 months.

👤 B2C Customers (individuals / end users)

All new products come with a 2-year legal warranty, in accordance with European regulations.
Refurbished products come with a minimum 1-year warranty, unless otherwise specified in the quotation.
Batteries and power supplies come with a 6-month warranty.
This warranty does not cover damage caused by misuse or electrical overloads.

What does “refurbished” mean? Are these used products?

A refurbished product (REF) is equipment that has been previously used but has been inspected, tested, and certified by our technical team to ensure optimal performance.

Unlike a simply used product, a refurbished one goes through a complete process of inspection, cleaning, repair (if necessary), and quality testing. It may show minor cosmetic signs of use, but these do not affect performance.

🔍 Product Types at MercadoIT:

REF – Refurbished: previously used, tested, and certified for renewed use.
NIB – New in Box: brand-new, sealed in its original packaging.
NOB – New Open Box: brand-new product with opened packaging.
WS – Official product from Cisco’s Wholesale program.

We always clearly indicate the condition of each product so you can choose with complete confidence.

Why choose refurbished instead of new?

Choosing refurbished equipment is a smart decision: you save costs, maintain performance, and contribute to sustainability.

💸 Up to 90% savings compared to new.
⚙️ Guaranteed performance, tested and certified.
🌱 Commitment to the circular economy.
🚚 Stock available for immediate shipping.
🔁 Ideal for maintaining EOL/EOS equipment.

It is a cost-effective, reliable, and responsible solution for any company.
