I think the neco headset isn't worser or better than a fsa or ritchey headset. You need to do regular maintenance on the headset. It's important to prevent water in the headset by using enough grease. Just before the winter do some extra maintenance.
For now, you can clean the bearing in your headset, re-grease them and use them during the winter period. And replace them after the winter.
In the 1,5 year I'm riding with my Chiner and Neco headset, I replaced the bearing recently.
