I have no desire to badmouth any product from a quality supplier. My intent is to simply state my experience with CCT's.
Somewhere around 190K miles my engine developed a nasty noise. At that time I replaced my OEM CCT with the one to which you are referring. Prior to that time I had no codes or performance issues relating to the CCT. The noise ended up being the water pump. The pads on my OEM CCT showed signs of wear but were still intact.
After about three months I began to get cam position codes (P0011/P0012). I had never had any cam related codes in the previous 190K+ miles. I contacted the supplier and they graciously replaced the CCT. Along with the new CCT I also decided to replace the cam chain and the cam position sensor.
When I received the new chain I compared it to the old chain. I checked the chain length with a jack screw. There was no measurable length difference between the new chain and the old chain. I checked the chain sag. Again, no measurable difference. I checked the chain link diameters with precision micrometers. Again, no measurable difference. The OEM chain with 190K+ miles was essentially as good as the replacement.
I also checked the oil pressure to make sure I didn't have an issue with low oil pressure. My oil pressure was excellent. Well within the specs for a new engine.
I replaced the CCT with the new CCT along with the chain and position sensor. Once again after about three months I began to get cam position codes. At this point I contacted the supplier. I returned the second CCT and received store credit for my purchase. I then replaced the worn pads on my OEM CCT and reinstalled it. It has now been ~ 35K miles since I put the original CCT with new pads back in place and to date I have had no issues whatsoever.
I had spoken at length with the supplier when I was going through these issues. At that time they had sold several hundred of the same CCT that I had purchased with no other complaints. I guess it's possible that I just happened to get two defective CCT's. Who knows? When I posted my experience in this thread it was apparent that many others have had issues with CCT's other than OEM. You can draw your own conclusions.
