As with everything, it's a matter of taste. For myself, I don't really find much special or unique about Fossil products. That said, many items are nice. We bought a watch for our daughter that allows the strap to be changed easily. She also got two or three straps. That was cool. But I don't know if that's unique to Fossil. Certainly the wallets and bags and "stuff" wasn't unique (except for the "Fossil" logo).
Staff is friendly and happy to help. Prices here are better than their non-outlet stores for the most part, though I think that's at least partially because they have a large sale table set up most of the time.
If you like their stuff, it might pay to see if they have what you want here and compare to a non-outlet branch.
