Query: Useless

I bought this product in the store for 79.99, I wish I had done my homework on it first. At first the product worked fine, yes there was static but I would just find a new station to avoid this problem. The real problem was in the manufacturing. It would constantly get stuck in my Plymouth Neon's charger port and every time I would try to remove it the rubber part on the end would get stuck! I've spent hours messing with this thing and blowing fuses trying to get it out. Also, when going around corners it slips dangerously knocks my ipod onto the floor by my feet while i'm driving. Totally useless.
