Why does an Amazon product get 1-star reviews?

Across products, the same reasons come back. What differs is the mix, which is why you need your own numbers.

1. Defective on arrival / poor quality – product fix: factory QC.
2. Not as described – listing fix: claims, photos and colours must match the real unit.
3. Size or fit – listing fix: dimensions in cm and inches, a size chart and a scale photo.
4. Fails after weeks – product fix: reinforce what breaks.
5. Shipping damage – packaging fix.
6. Missing parts – a "what's included" image and a packing check.
7. Hard setup / bad instructions – a quick-start card and a video link.
8. Battery / power – state real-world battery life.
9. Compatibility – list what it does and does not work with.
10. Smell, value, used items, service – smaller but often severe.

In our Echo Dot sample, only about 1 in 5 complaints looked preventable with a clearer listing; the rest were performance, software and durability. For a typical private-label product the mix is often very different.
