Query: Dont waste your money

I was so excited when I got this. I took it on a look road trip, and well I couldnt use it half the time because of the radio picking up to many stations. Normally this wouldnt be a bad thing, but the transmitor in this device sucks! I tosed it out at a Walmart, and went inside the store got me a durabrand one, it works like a dream and was only $12. I think my new modulator would override oneelses radio going down the highway a few cars away!
