I have that exact kit... It's not as bright as they show in that picture, you can't see them during the day. They're mediocre brightness. Got the kit for $200CAD w/ shipping so it's alright I guess. The remote sucks nuts to say the least also. I like how they seem to "forget" to mention in that persons ad that it can only stay solid on 17 colours.
That seller seems like a dick, he doesn't tell you what you're really getting. Here's who I bought it from, everything as advertised. Shipping took less than a week (international). I was very pleased, I'd suggest him.
I'll upload a pic of my car with it on in red to give you an idea of what you're getting. Don't mind the quality, webcam..
Remember, this is 100% the same kit as that one, so what you see is what you're gonna get.
