Never got on with them myself and always had them removed from the bikes I've bought with them fitted. No doubt that freshly installed and correctly set up they work well, but the one's that I've come across have been neglected to the point that they no longer work and it's more trouble than its worth to try to get them working again (confirmed by workshop mechanic).
I prefer to clean and lubricate my chain personally on a regular basis, it gives me the opportunity to check on chain slack, tyre condition etc.
