I have a pair on my bike, same seller I believe. First off the ones I have on my bike are NOT waterproof or resistant. Had found that out after a wash and I kicked them on now I have a pencil eraser sized hole in one. The ballast went out on one kanji in a week and the same day on the gsxr1300 logo. Seller sent two ballast to me just paid shipping. I have problems with adhesion even after meticulous cleaning of the surface . I followed the video instructions to the best of my ability. I had ordered white kanjis and after installing there now a very light bluish/white, looks like a cloud kinda. That might be from washing though. After install I received the email stating they weren't waterproof that I would be not to get wet and recommended clear coating them. If I was clear coating over them they would be perfect. If they stuck better I wouldn't have an issue but I do get tons of compliments and for the price it's hard to beat. The other option is gator glass...
