This might be Germany specific, I don't know. People seem to order stuff, use it, then send it back, and Amazon sells it as new (which it isn't - just like cars, you buy it and drive it, it's a used car).

Used items: Electronics, DSLRs, mirrorless cameras, lenses (especially bad, has someone dropped them?), latest (this week) was a Gardena water splitter. I mostly by somewhere else if possible today (Bauhaus for garden stuff, Mediamarkt for electronics, cameras from my local store).

It doesn't help that too many manufacturers don't seal their packaging.
