Is a FSA account worth putting money into if my employer gives good health insurance?

I am currently filling out paperwork for a new job that I will be starting soon. I just went through and chose all of my healthcare plans and its looks like ill be paying nothing out of pocket each month for premiums. These plans also are $0 deductible or just like $100 deductibles. With this I was wondering if it would even be worth it to open an FSA and put money into it if I often will never pay a deductible or will be done with my deductible after one or two visits. Any advice is appreciated.
