I wanted the wide gear range available in this cassette and also was glad I could get it at a decent price. I have one of these on another bike and it has lasted a very long time. This one should also last a long time. This is a very good cassette that I'll buy again if the need arises.

ongoing maintenance

started to have poor shifting while on the trainer and realized lubrication was not the issue. Worn cassette and idler wheels were actually the culprits. Installed new cassette and idlers-voila! problems solved

Fast delivery.

The cassette is lighter than the 105 version and feels like it delivers smoother shifting. Not as light as Dura Ace but more durable and more value for the money spent.

Reliable smooth shifts

Have these on two road bikes. Cannondale Evo Hi Mods- one with DI2 and the other with Dura Ace year. Pretty simple works well all the time with both set ups. Minor weight penalty vs DA cassette but not noticeable. Have one less adult beverage and you made up the weight difference.

I purchased the Ultegra cassette to add to the Shimano Ultegra wheels that I had ordered from the vendor.

Very pleased with the cassette and wheels. No problem installing on bike.

I had a 11x28. I talked to my coach about the climbs we were planning to do. I switched to this and was happy I did!

Sure, DA is a little lighter, but Ultegra is a far better value.

This cassette makes my rides more enjoyable, I expect it to last a long time given Shimanos reputation.

I use it for mountain climbing. Long grades above 10% require me to stand in a 34x28, so this just makes the difference between sitting and standing.
