I already had speakers, but I'm interested in cars and was drawn to the description "The roaring engine sound echoes!!" lol. When I actually used it, the size was surprisingly large and the sound was a bit loud. It can also light up, but I think it looks more stylish without it lol. As for the engine sound itself... it really sounded like an engine and was loud enough to be called "roaring" lol. I think it's worth buying even if you're not a car enthusiast. - Bluetooth compatible - Radio function included - Various lighting patterns - 3-way speaker (also playable from USB/microSD card) - No scratches - Almost unused Please purchase it from me.
