I've had a Deuter Futura 28 pack for years, had no problems with it and it's been used for day hikes, as a "cabin" sized bag for flying, and for taking lunch to work. It's very well made and I'd certainly consider Deuter packs again.
When I proessed returned items for an outdoor retailer we saw very few Deuter packs returned compared to other brands, and to see one with any kind of fault or damage was rare indeed.
