Review on 🚵 CYSKY 10 Speed Cassette 11-42 for Mountain Bike, Road Bicycle - Lightweight & Compatible with SRAM, Shimano, Sunrace Freehub Body by Charles Butler

It's been riding hard uphill and downhill for 5 months. The teeth are stripped off the smaller rings, allowing the chain to slip every now and then when trying to pedal hard in the fastest gear. My B-bolt on my derailleur was set far from the cassette, so part of the damage may have been caused by that. In general, for such a price is not bad, it does its job, but it is not perfect. If you're in an elevator and want something cheap, this is a decent option. If you're a big climber, you might choose a higher quality option.
