well actually you are quite lucky to be able to benefit from this insurance as it is only available for students, temporary workers, university research staff etc. The "normal" insurance with say 1500 CHF franchise would cost you something like 300 CHF
Now that you are happy to hear above, depending on how often you go to doctors you could opt for a higher franchise cover and pay less per month, but since the difference is not much so you could even go for 300 CHF franchise.
And yes, by all means go for this cover; I know many people who were with swisscare and all of them were happy.
