You can save money and help save the planet by buying used or refurbished electronics instead of new devices. Since most of the environmental impact of devices comes from the manufacturing phase, buying secondhand gear can reduce your carbon footprint. Do it right, and buying refurbished can feel much like buying new. This guide delves into what you need to know about refurbished terminology, offers tips on what to look for to snag yourself the best deals, and lists some of the best places to buy refurbished gadgets and used electronics.

What Does Refurbished Mean?
There is no legal definition of refurbished. Some sellers prefer used, pre-loved, secondhand, reconditioned—the list continues. Refurbishment implies that the seller has tested the device and may have repaired and cleaned it, but the only way to be sure is to read the fine print and understand what the seller means by whatever term is used.
If you’re lucky, you may get an open-box device, which a buyer has opened but never actually used. Sellers are not legally allowed to resell returned devices as new, and it’s common for all returns to end up sold in the same place. At the other end of the scale, you may end up with a device that looks like it has survived the apocalypse and doesn’t work.
Tips for Buying Refurbished
I’ll recommend a few good places to buy refurbished electronics below, but first, let’s explore what you should look for in a seller and what you need to do to protect yourself when you buy.
While buying older electronics is often a great way to save money, there are a few things to keep in mind. It may make more sense to buy a discounted flagship phone from a couple of years ago than a brand-new budget phone, for example, but there are also some potential cons. Always consider software updates and ask:
- How many more years of software updates will the product receive?
- How long will it continue to get security updates?
- What version of the software does it come with?
- How easy is it to update the software?
Aside from working out what the seller means by refurbished, you should read the listing for any potential purchase very carefully and try to answer questions such as these:
- Has it been tested, and does everything work?
- Does it have a new battery or a guarantee about battery health? (This is crucial for old phones and laptops.)
- Has it been wiped if a previous user set it up?
- Is there any cosmetic damage like scratches or cracks? (Look for a transparent grading system.)
- What is included? (Does it come with chargers, cables, manuals, and original packaging?)
- Is there any warranty offered? (The longer the better.)
- If there is a problem, how do returns work? Do you have to pay, and what is the return window?
If you’re uncertain about anything, it’s worth asking before you buy to avoid disappointment.

There are protections for purchases, such as Section 170 of the Fair Credit Billing Act in the US or Section 75 in the UK. But you should use a credit card for purchases to get the best charge-back protection and avoid going through a third-party payment service, such as PayPal. Some banks and credit card companies are better than others, so it’s worth researching their reputations and the protections they offer.
If you can inspect and test devices before you buy, do it. Otherwise, you should closely examine and thoroughly test any device you buy immediately when you receive it. Remember that there is a limited window to report any faults or issues with the condition and return an item. Always keep the box and packaging it arrived in at least until you are satisfied that you won’t need to return it.
You’ve done your initial tests and decided that you are keeping the refurbished device you bought, but there are still a couple of things you might consider doing before you start using it.
Best Places to Buy Refurbished Electronics

You have an enormous choice when buying refurbished electronics, so let’s break down your options.
We have had some good experiences buying refurbished devices from their original manufacturers, which makes sense since they know precisely how to test and repair their own devices. All of these manufacturers certify the refurbished devices they sell, and most offer at least a one-year warranty, but the savings vary; for example, Apple offers up to 15 percent off, while Dell offers up to 50 percent off.

![Scientists Built Amphibious Cyborg Cockroaches and We Regret to Inform You They Work
The humble cockroach: depending on where you live, they’re variously the bane of apartment dwellers, a tasty snacc, or a source of political inspiration. The cliché is that they’d be the only creatures to survive a nuclear apocalypse, and whether or not that’s true, you probably wouldn’t put them first in line for further enhancements to their already legendary ability to survive. However, it seems that no one’s told that to the folks at Nanyang Technological University in Singapore, because a group of researchers from the university’s School of Mechanical and Aerospace Engineering recently published a paper describing the process of fitting a cockroach with a diving suit. As the paper’s abstract explains, “The suit integrates a miniaturized oxygen generation module with a flexible waterproof shell, enabling continuous oxygen supply and isolation from surrounding water.” Or, in other words, the suit successfully allowed the insect to breathe underwater, turning it into a sort of nightmarish amphibious cyborg. If this sounds like a terrible idea at face value, console yourself with the knowledge that these cyber-roaches are designed to be used for benevolent purposes. As per the paper, said purposes include pipe inspections, “object transportation,” and, apparently, search-and-rescue missions. (Smash cut to 2031 and Elon Musk ranting about a “pedo roach”.)
Research into the creation of cyborg insects has been a thing for some time, both in academia and in the world of tech. On the latter point, readers may remember the RoboRoach, a $200 DIY kit for creating your own cyborg cockroach that was funded via Kickstarter in 2013. The kit is still available, and these days it seems to be marketed as a fun activity for kids—on the manufacturer’s website, it’s labelled as being for “Grade 9+” and “[Requiring] supervision.” If the idea of a bunch of 15-year-olds performing surgery on cockroaches makes you kinda queasy—supervision or not—well, you’re not alone.
Let’s get back to the Nanyang Technological University, where the experiments are presumably not being conducted by middle-schoolers. If you’ve ever wondered how a cockroach breathes, the paper explains that “like most terrestrial insects, [they] breathe through thoracic spiracles that take in oxygen directly from the air.” The “diving suit” is basically a flexible waterproof shell into which a miniature oxygen generator pumps oxygen, effectively creating a tiny breathing bubble around the insect’s air-intake thingamajigs. This allowed the insect to breathe underwater for up to three hours, although it seems there were some initial, um, design issues to sort out: “Dorsal mounting of the oxygen generator on the cockroach created significant water-resistance during underwater locomotion… causing postural instability and rollover.” Once this issue was resolved, it seems the roaches got on just fine underwater, exhibiting “stable and smooth underwater walking without rollover.” The researchers conclude that the idea is a winner, and that it could be “potentially extended to other terrestrial cyborg insect platforms, such as [other] cockroaches, locusts and beetles.” Amphibious locusts!
