I've had premium membership for almost a year now. At the time of writing this I still have five days of premium membership left.
Will I get another subscription? Probably not. The thing is that I don't think there are enough advantages you get when you have premium. Just losing the website ads and getting some extra things you can place on your page isn't worth the price of about 20 euros.
So yeah, I'm not quite sure yet whether I will renew my premium membership. I guess time will have to tell.
