Working fine
So far so good, installed perfectly and working great. Note; I have the 50t and the appearance is slightly different than pictures (the lightening slots are much more prominent, which is to be expected.) They seem perfectly symmetrical so I installed mine backwards so the logo faces inward, I prefer the "clean" look this way.

Awesome
Perfectly made high quality product. Fitted to my Super 73 RXE like a glove. Original was 44 tooth which I replaced with a Deckas 52 tooth. The desired outcome was more range and ability to use the 10 speed efficiently. Highly recommended this product.

良いですよ
GIANT ESCAPE R DISK LTDをシングル化するためラウンド42Tを購入。 クランクはそのまま使用、ボルトも短く加工すればオリジナルを使用出来ました。 (コッタレス抜かなくても付け替え可) ナローワイドなので大丈夫かなとは思いますが、私は念のためチェーン落ち防止デバイスを取付けています。 音は静かな方だと思います。 デザインにセンスを感じないので星ひとつ減らしましたw

Solid AF chainring!
These are surprisingly very good chainrings! I had 3 of the 4 little rivet looking bolts that hold them to the crank arm come off on a pretty long ride and I didn’t notice until the 3rd one popped off and then it twisted up in my chain and you would think it would have bent the crap out of it cuz of the way I ride my bike, but Nope! It was completely straight and teeth all in tact! It surprised me how durable it is for how inexpensive it is. I will be purchasing again for sure!

Excellent choice to reduce chain slap issues
Make sure you have the right size and double check the large tooth fits in your chain :-) I love this gear!
