Back Market

Back Market is the most widely cited refurbished-electronics marketplace internationally, with more than 5 million customers and a presence in more than 150 product categories. This audit evaluates its website and app as a digital product — how you compare, buy and manage warranties — not the company as a business.

What Back Market is

Back Market is a marketplace connecting buyers with certified professional sellers of refurbished electronics: smartphones, laptops, tablets, consoles and home appliances, among other categories. Unlike buying second-hand between individuals, every seller goes through a certification process and offers a formal warranty on the product sold.

Search and filters: the specific challenge of a refurbished marketplace

The biggest challenge for this type of marketplace is making clear to the buyer exactly what they’ll receive, since the same model can have a different cosmetic condition depending on the seller. Back Market solves this with specific filters — cosmetic grade (fair, good, excellent, premium), capacity, color, warranty length and seller — that let you compare options of the same model in a fairly granular way before deciding.

Product page and checkout

Product pages explain, with real photos and clear descriptions, what physical and functional condition to expect for the chosen grade, plus the seller’s specific warranty terms. Checkout is what you’d expect from a mature marketplace, with no notable friction.

Mobile app: one of the strongest points

The app, available on iOS and Android, has an aggregate rating of 4.6/5 and has surpassed 10 million downloads. It mirrors the website’s catalog and filters well, and adds order tracking with notifications that users themselves rate positively.

Reputation and real reviews

Back Market Spain has accumulated nearly 40,000 reviews on Trustpilot with a 4 out of 5 rating, one of the most solid figures in volume and consistency within the refurbished-electronics sector. On Trusted Shops, another trust seal common in European ecommerce, the rating is even higher: 4.70 out of 5 across nearly 2,400 verified reviews, rated as “excellent.” The most praised aspects are fast delivery — typically within 24-48 hours — the good overall condition of received devices (reviews describe, for example, an Apple Watch received with 99% battery health, or an iPad Air with 100% battery health and zero charge cycles), and a well-explained purchase and activation process.

The most repeated criticism in negative reviews points to the variable quality of some non-original replacement components, such as batteries, especially on high-end models where degradation shows up earlier than expected, along with some cases of slower-than-desired after-sales service when handling an issue. It’s worth qualifying this: people with a bad experience are more likely to leave a review than satisfied ones, so these figures likely over-represent problem cases relative to the real average experience across the millions of orders the platform handles. Even so, as of this audit (September 2026) this is the available data, and we report it honestly.

Warranty and inspection process: the backing behind the low price

Every unit, as the platform itself states, goes through an inspection process of up to 100 checkpoints before being listed, reviewing sensitive components such as screen, cameras, connectivity, speakers and battery condition. On top of that comes a standard 24-month warranty against material and workmanship defects — well above the legal minimum in many markets — and a 30-day trial period to return the product with no need to justify a reason. It’s this set of guarantees, more than the catalog itself, that underpins the confidence needed to buy refurbished second-hand electronics online.

Digital customer service

Support is handled via chat and form, with warranty and issue management integrated directly into the user account. The after-sales experience can vary depending on the specific seller within the marketplace, something inherent to this business model.

Who it makes sense for

If you’re looking to save on mid-to-high-end electronics and value being able to compare the exact condition of each unit before buying, backed by a formal warranty, Back Market is a solid option as a digital product. If you need the device with 100% original factory accessories and packaging, or are very sensitive to replacement battery life, it’s worth carefully reviewing each specific listing’s terms before deciding.

Affiliate disclosure

Product Auditors participates in Back Market’s affiliate program through the Awin network. If you buy through the links on this page, we may earn a commission at no extra cost to you. This commercial relationship does not influence the editorial assessment: the score and conclusions are based on the site’s public documentation, the app’s public listing, and verified reviews from real users.

Methodology for this audit

This analysis is based on public browsing of the website, the app’s public listings on the App Store and Google Play, and verified reviews from real users published on Trustpilot, checked in September 2026. It does not substitute for an actual purchase with full order and warranty tracking. You can read more about how we work in our editorial methodology.
