OK so anyone who has used Keith Mcmillen products will know that they have a horrible rubber sticky coating on them which attracts dust. I laboriously took that off as underneath is just a nice normal surface. However taking off that film means the writing is removed from the controller too so I wrote all the short cuts on the keyboard then sprayed it with a gloss coating that as smooth as smooth can be. This item works 100% and is now not a dust magnet and has a protective gloss coating on it thats a treat to use. You can also update the software the Qunexus red which is a game changer without having to spend £250.00 on a new one or around £150 for a second hand one. Grab a bargain. Free UK postage.
