Cheap and effective
I converted a couple bikes to 1x set-ups, but I had problems with losing my chain. I installed this chain deflector to keep the chain from falling to the inside. Once it is installed, it works well.

The shape of the guide is good. Turning it about the seat tube lets it reach to the middle chainring. The curved/tapered tip seems to work well to keep the chain in place without snagging. I have not had any problems when it's installed.

My complaints are that the hose clamp that holds it on is not retained inside the deflector. Installation requires holding the deflector in the right place & pushing the clamp into it while tightening. Also, the hose clamp will scratch your frame if you aren't careful (or even if you are), especially when trying to remove it.

Similar products that have a screw directly through the plastic are probably better, and I will try that style instead of buying this one again. If you have a problem with chainsuck, I highly recommend this TYPE of product because it's cheap, simple, effective, and light. However, I would not recommend this specific BRAND because of the problems with the hose clamp.

PROS: Cheap, Simple

CONS: Too Cheap

Great Item for the Price
Simple to install. Keeps the chain from falling in. Does little to stop the chain from jumping out.

I would not...
I would not recommend this product. There look to be other types that do the same thing and a few bucks more expensive, that are probably more solid

Plastic case does...
Plastic case does not capture the steel band clamp, which causes it to slip off the band clamp when loaded. Wedge-style design of plastic finger causes it to jam the chain before breaking off. Case is too tall to fit most bikes as it interferes with the downtube unless some sanding is done.
