Works great, easy to install and good fun playing with the different colours and flash patterns. Only thing I would improve is if it could allow for single colour flashing and fading or use the whole range of colours (options are either 3 colour or 7 colour cycle, but control allows for 16 colours individually).
Great case decoration, though, especially if you're like me and like to change things up regularly.
*edit: After using the product for a couple of weeks, the colours have started not matching the appropriate buttons on the remote. Randomly swaps red for blue or blue for green, and the mixed colours (purples, oranges, etc) have all gone out of whack. this may be a random fault and isn't so much of an issue as I just leave it on the slow fade cycle now anyway, but as a result I'm reducing my rating to 3 stars.
