Buying Tested Electronics: 7 Tips for Smart Deals on Returns

The booming market for returned electronics

Smartphones, laptops, tablets – they are among the best-selling products in German e-commerce. And they are among the most returned. For 2025, experts predict around 550 million return parcels in Germany alone – a new all-time high. Almost every fourth package ordered online (24.2%) is returned to the retailer.

What many people don't know: A large proportion of these returns are technically perfect. The devices were unpacked, briefly tried out – and sent back. Instead of being resold, they often end up in the reconditioning chain or, worse still, in disposal. This is exactly where the market for tested returned electronics comes in – and offers buyers enormous opportunities.

What distinguishes tested electronics from "simply used"?

The term "used" from private sales and "tested returned goods" are worlds apart. With tested electronics – whether declared as B-stock or refurbished – every device undergoes a systematic quality process before resale.

Professional providers test, among other things:

• Processor performance and RAM

• Battery capacity (often a minimum value of 80% is guaranteed, otherwise the battery is replaced)

• Display, speakers, microphone

• All connections, WLAN and mobile phone modules

• Sensors such as Face-ID or Touch-ID

A private seller cannot provide this. So if you buy tested goods from a retailer, you know exactly what you're getting – and you also have legal protection.

The 7 tips at a glance

Tip 1: Read and understand quality grades
Reputable retailers categorize their goods according to clearly defined grades (A, B, C or "Like new", "Very good", "Good", "Acceptable"). These ratings refer exclusively to the appearance – not to the function. A Grade B device has scratches but 100% performance.

Tip 2: Insist on complete condition descriptions
Look for honest, detailed product descriptions. Every defect – even a non-functioning USB port or a cracked display glass – should be explicitly mentioned. If this transparency is missing, caution is advised.

Tip 3: Check warranty and guarantee
The statutory warranty also applies to B-stock and returns. Many reputable retailers also provide their own dealer warranty of 12 to 24 months. Compare the conditions before you buy.

Tip 4: Use your right of return
When buying online, the 14-day statutory right of withdrawal applies – many retailers even grant 30 days. Use this time to extensively test the device: charging speed, battery behavior, all connections, all functions.

Tip 5: Pay attention to certificates and seals
Reliable providers display TÜV tests, ISO certifications, or memberships in sustainability initiatives such as "Green IT". Such seals are not a marketing gimmick, but a real quality indicator.

Tip 6: Analyze customer reviews specifically
Reviews on independent platforms such as Trustpilot or Google provide valuable insights into delivery reliability, actual device condition, and customer service. Pay particular attention to the type of negative reviews – individual points of criticism are normal, systematic complaints about incorrectly described conditions are a warning sign.

Tip 7: Price comparison within quality grades
Don't just compare retailers with each other, but also different grades from the same provider. Often, the price difference between "Like new" and "Good" is considerable – while the optical difference is minimal. Those who are flexible can save even more here.

Understanding quality grades: Your compass when buying

Not all retailers use exactly the same nomenclature, but the basic principle is the same everywhere:

 

What to look for in warranty and returns

The most important message first: Your rights remain fully intact. The statutory warranty also applies to tested returns from commercial retailers. A restriction to less than 12 months is legally inadmissible for B2C sales.

Specifically check:

• Does the dealer warranty also cover battery problems? Many limit this.

• Is return shipping free? According to studies, 30% of German consumers don't even order if the return conditions are unclear.

• Is customer service accessible? Phone or chat support is a sign of a responsible retailer.

Common mistakes – and how to avoid them

Many buyers fail not because of the product, but because of avoidable mistakes when buying:

• Only looking at the price: The cheapest price is useless if the warranty or description is missing.

• Ignoring grades: Anyone who pays for Grade A+ but gets Grade C – and doesn't notice it – has negotiated poorly.

• Missing the return deadline: Test your device immediately and systematically. Don't wait until day 13.

• Not checking battery condition: Fully charge the device and observe the battery life on the first day.

• Overlooking missing accessories: Power adapter, cables, charger – are they complete or just "possibly different"? That belongs in the description.

Conclusion: Smart buying pays off

Tested returned electronics are not a compromise solution – they are the smart alternative to buying new. With savings of 30 to 60% compared to the new price, full legal protection, and professionally tested devices, there is hardly any rational reason to always opt for a new device.

The market is growing, the offering is getting better – and those who understand the quality grades and ask the right questions regularly find real bargains. At the same time, you actively contribute to the circular economy: Every tested returned device that finds a new user is one less device in the disposal chain.
