Query: Great but too expensive

I've tried this product for the last 2 weeks including a 13hours road trip.Work flawlessly all the way. The sound is great and the transmitter is prety powerfull.I could transmit to another car from around 50 feet away.The only thing bad I have to say is that the price is too high.I paid 40$ for this and it has zero features beside 3 preset. The thing does not even come in a box.It was shipped in a bubble bag with a cheaply printed 1 page instruction manual all this in a bubble enveloppe.The product is great but not worth 40$, more like a 20$ would be fair. For 40$ you have other product with a lot more features that get good reviews but I haven't tried them so I don't know how good they are.All in all, this product works perfectly, it's just too expensive in my opinion.
