Secondhand Devices: What you need to know

Secondhand FoodMarble Devices – What You Need to Know

If you’ve seen an ad for a secondhand FoodMarble device online, you might be wondering if it’s a good idea to buy one. While it can be tempting, there are some important things to consider before making that decision. Our priority is your health, safety, and overall experience, so here’s what you should know.

1. Health and hygiene risks

FoodMarble devices are designed to be personal digestive breath testers, and they do come into contact with bodily fluids such as saliva. Because of this, there are real hygiene risks when using a secondhand device.

It’s also important to note that a FoodMarble device cannot be sterilised with alcohol-based cleaning products. In fact, doing so may damage the delicate sensors inside. For this reason, we strongly advise against using secondhand devices.

Your health and safety are always worth prioritising over a potential bargain.

2. No FoodMarble warranty cover

Every new FoodMarble device purchased directly from us includes a 1-year warranty covering any manufacturing defects. This gives you peace of mind if something goes wrong.

Unfortunately, secondhand devices are not covered under warranty, which means if your device develops an issue, we won’t be able to replace it under our policy.

3. No returns policy cover

When you buy directly from FoodMarble, you’re also covered by our returns policy, so you can request a refund or replacement if you change your mind before opening and using the product(s). This protection does not apply to devices purchased through third-party sellers.

Final thoughts

We know it can feel appealing to pick up a secondhand device, but in the long run, it may put your health at risk and leave you without support if something goes wrong. Buying directly from FoodMarble ensures you get:

• A brand-new, hygienic device
• Full warranty coverage
• Access to our returns policy
• Peace of mind knowing your health and safety come first
