Works well, had to do some filing of mating surfaces to get this to fit my cranks. Not a deal breaker, just an annoyance.

This chainring is good value, and unlike others the included fasteners worked perfectly- my chain drops are also solved! But, I will concede that it doesn’t feel as stout as even the stock chainring (definitely won’t last 1000+ Kms if that what you expect). But, great for the casual trail rider/1x conversion.

Works as it should with the adapter and barely moved my chain alignment. ALSO SUPER LIGHT. 10/10 for the money and quality. Will be buying more of these sprockets in different sizes.

I've used sram and race face before and this one works just as well. Has a few hundred miles on it with no issues. I have no doubts it will hold up just fine. Converts your 2x or 3x to 1x. So worth it!

This is a perfectly fine chainring for a great price; I've had no issues with regular use all summer long. It has held up with no problems, functions well with my SRAM drivetrain (12 speed). I was able to replace the old chainring myself although the included fasteners didn't fit my old crank because of the ring-guard, so I'm using the old nuts. No problems, I'm satisfied and it was about half the price of other similar options online.

I bent my other chain ring which did not come with mounting screws, so I had red necked something together with some bolts and screws. Which started to rust and were ugly. So it's really nice that they included mounting screws. Overall I have not had the chain fall off yet, even tho my bike is not made to be a 1x8, and the derailleur doesn't stay in place and makes the chain fall off on bumps, but that has not happened yet. I am very pleased with this.(Please note to anyone converting their bike into a 1 by, make sure your derailleur is made for it first. my bike can no longer go on trails till I get a new derailleur.)

So far it looks like a solid chainring. The chainring came with the four bolts needed to install, the bolts look like if they were chromed out. The gold color is great and the milling looks like top quality! I got the 32T and it is pretty light weight!

Chainring looks good, pretty disappointed that it won’t fit my crank though. The bcd on my crank is a 104 bcd and the chainring I order is also 104. The tabs are to long and you shouldn’t have to “make it work”. I should have just ordered a raceface.

Un plato muy ligero y bien mecanizado que tiene una relación calidad precio muy buena. Espero que no se desgaste pronto con el uso. La cadena se fija muy bien en los dientes narrow wide y no se sale en saltos y baches

Update: The seller contacted me and was excellent about refunding the purchase. I've left the original comments below just for informational purposes.-0 star: There is no recess (sink) for the chain bolts like other brands of chainrings have. This makes the nut stick out instead of being flush. Only buy this product if you have lots of clearance behind the chainring. It won't work for most mid-drive electric bikes because of this.-0 star: The product description says "Each chainring come with 4 bolts." Mine did not come with any bolts.+5 stars: Other than the above, the product looks exactly as in the pictures and as described. It seems to be good quality for an aluminum chainring.Note: It took over month or more for this product to arrive.Note: All the product details written on the package appear to be a raw Google translate. No English speaker reviewed text. It's quite humorous though. Fun example: "Conversions, single plate, the vehicle to dip before the dial before transmission line transmission pipe and three piece tooth plate, the vehicle can reduce 1 kg weight, make the whole car Looks more simple, beautiful and performance coexistence."
