I have used these for several years on my road and mountain bikes. They have functioned flawlessly, with absolutely no problems.
Note that these will work on any 9sp chain, including Shimano and Sram.
Buy a pack of these. Put one on your chain to make it easily removed for cleaning. Also keep on or two in your pack or seat bag in case you break a chain out on the trail.
