The crescendo stitch quality is great, never had any bad stitches with anything I have sewn including FMQ. The machine is quiet not like some that sounds like thrashing machine. The lighting is great and easy to adjust. I haven't used the sensor pen yet. The dual feed foot looks like it would be hard to use but I found its very easy to operate just getting use to it because it is so big. I have only had one issue with it, I had trouble at times when I have multiple layers I heard loud clicking sounded like the metal where the needle bar goes up and down in the housing was hitting something and I have had to take bad to dealer once but it is now doing it again so off to the dealer which this is aggravating other than this I love my crescendo
