    I need one! Shimano 105, changing from big to little, every now and then the chain comes off. Potential for a nasty case of chain suck.
    They're pretty much hidden out of the way, weigh very little and could save a lot of hassle.

    I have a Rotor one, it's on the bike but it's never been needed.

    No harm in having it on there and it was only a fiver as the shop put the wrong price on it.

    I have one, you need to set them up correctly though for them to work you need the gap between the smaller chainring with the chain on it to be small enough it wont catch but not so big the chain can slip through.
    Also make sure its done up tight the chain will try an slap through with a fair amount of tension from your pedal stroke and the mech spring.

    I have Deda Dog Fangs on both bikes. The CR1 frameset came with one supplied in the box. Seems like a sensible precaution.

    No idea if they've ever averted a dropped chain. No obvious abrasions if they have

    I bought one after the chain came off and ate some paintwork. Not sure if it's been required since then, apart from a few weeks ago when I came off the bike - the chain came off, but was held up by the chain catcher. Worth having for peace of mind imo.

    I agree and I had almost the same experiences. Now I have a Deda Dog Fang on one bike and a K Edge on another. IMHO for the amount of money they cost, there's not a lot of reason not to.

    The Dog Fangs are good but won't fit a lot of modern carbon frames where the seat tube flares out towards the bottom bracket.

    Had one of the other kind (K edge) on another bike. Grest until one day when my chain came off and somehow was forced in between chain catcher and chain ring. Was impossible to get out by hand and as I didn't have a 3mm Allen key to remove the chain catcher the ride was over.

    That's true. Mine wouldn't go low enough on the CR1 when I fitted a triple chainset.

    Exactly the same for me, four mile walk home.
