Not a panacea

This works OK, but it is not infallible for mountain biking. For the most part, it has kept the chain where it is supposed to be. When it fails, it can becomes a hassle because the chain will jam itself between the chainring and the guide. Also, it seems to be susceptible to being bent during a crash or even as the result of striking the guide with your heel while pedaling up/over/around technical obstacles. At one time, it acted like a wrench and loosened my drive-side bearing cup, causing the guide to spin around and lock up my chain.
I use a narrow-wide chainring now with no guide and an old-school derailleur (no clutch). Only a few rides in, but the chain has not fallen off and if it does, it will be much easier to re-mount. Lighter and cleaner look, too.

Pros: It works most of the time

Cons: Not 100% reliable
Hard to re-mount chain when it fails
Aluminum mounting plate prone to minor bending

I found this guide easy to set up and highly effective when used with a 1x9 drivetrain. No dropped chains so far. If you don't need a full bashguard+chainguide+chain tensioner setup, this is a good option.
