Worth every penny
For lower michigan terrain a 1x setup rules the roost. I tried other keepers without success. I have been using this keeper for several months and have not thrown a chain.

PROS: Flawless Operation, Lightweight

CONS: Tricky Setup To Make Rub

Perfect for my 1x10 setup
The BB mount version DOES work on a Santa Cruz Superlight. I'm not sure what version the reviewer below used, but I had now issues with mine.

It works great and after 300-400 later, still no issues. Great product.

PROS: Lightweight, Easy To Install

The way to go for 1 x 9
If your setting up your ride to rum 1x9 or 1x10 this is the way to go. Now this isn't for bombing down mountains but it will keep your chain in place for trail riding.

PROS: Easy Set Up

Great Product
I can't believe I waited so long to go to a 1x drive train. I should have done this years ago. My chain always jumped gears up front, not any longer. Bumps, jumps, and log crossings no problem. Haven't had the chain come off once. It took about 40 minutes to install most of that was cleaning up my running gear.

PROS: Stable

CONS: Not soon enough

Does its job
Great alternative to a front derailleur. Works very well and haven't lost a chain.
It does cover some of the lower linkage on my suspension, which makes it a little annoying to any maintenance on it but that only happens once or twice a year.
I have the BB mount and that is a little finicky ie. when tightening the bb, it will move the guide so you have to be sure to brace it.

I should have purchased the direct mount. My bad.

PROS: Lightweight, Simple and effective, Inexpensive

CONS: Finicky to set up

Great guide, simple setup
Great guide, very simple to install and setup. Have been using their guides for almost 2 years now. I love 1.x setups and this makes it easy, plus if converting a standard triple the added spacers save you money over having to buy new chainbolts.

PROS: Light, Ease of Use

CONS: Price

BEST USES: Trail, XC

Just simply works
I used this on a Turner Sultan with a 34 tooth chain ring. I had to modify the mounting clamp heavily to fit around the gusset weld as well as the plastic notch on the guide itself so it would sit low enough. Most likely you wouldn't have to do this on other frame designs.

Once on it just simply works, no more dropped chains. Easy to adjust.

It would be 5 stars but a little pricey for what it is.

Compatibly limited, but does the trick.
The idea is there, but the design just needs a little tweaking. Compatibility is going to be very limited on MTB's with vertically mounted rear shocks. Bracket tensioning bolt comes in contact with shock on Giant Stance, heavy modification was needed and a divergent style tensioning bolt was needed for clearance. After about an hour of modification it performs just as advertised. And like other reviews have stated, overpriced to what it is. I would do your research on all frames with vertically mounted rear shocks unless you aren't gun shy about grinding on your new $100 part.

PROS: Attractive Design, Lightweight

CONS: Limited Compatibility, Difficult To Install

Looks good but it didn't fit on my bike.
This guide will not fit on the Santa Cruz Superlight frame. It will clash with the main suspension pivot.
