I have this on my Ultegra R8000 - https://www.aliexpress.us/item/2255800049110907.html
 And this with 105, https://www.amazon.com/JFOYH-Ultralight-Cassette-Compatible-sram-Silver/dp/B09B12QFHH

Both have been excellent. Can’t feel the difference between these and Shimano ones in shifting.

They are all fakes. If you don't want to wait 1 month delivery, here's one even cheaper with free 3-4 day shipping if you are in the USA

They are also on Amazon. These fakes can go as low as 12-14 bucks with free 3 day shipping from ebay. My last chain was $14 off of eBay. Not sure how long they last, I'm down about 1500 miles on it.

I've had hit and miss experiences with those cassettes, ordered a 11-50 for my MTB and were pleased, good shifting performance and light weight. Second purchase was a road cassette, having trouble with shifts to/from the alu monoblock into the first steel sprocket, the first steel sprocket was wobbling when i first mounted it (A year after my purchase, seller were gone from Ali  so warrenty/replacement were out).

Absolutely. It is a hit or miss. Exactly opposite to your experience, I had terrible experience with MTB cassette by Sunshine (both 11 and 12 speed) I just couldn't get indexing done. After I tried every trick on YouTube and elsewhere I gave up and ordered Shimano cassettes and life is infinitely happier since then lol. Surprising because road cassettes worked so well
