Ktec splitter looks good and may be a bit more durable than the genuine one. I have broken mine by hitting a brick left in the road, but when I was removing the bits, I could not believe how brittle the plastic was. I literally snapped it to bits in my hands with very little effort.
Also cant believe how expensive they are. I bought a Seat Ibiza one a couple of years ago which was much better quality flexible plastic, two interlocking pieces, much bigger, more detailed and only £30.
