Just flew them in Y from SFO to BKK. Awful seat, and the absolute worst food I have ever had anywhere on Earth! I could not sleep well in the seat. Make sure you have the space underneath the seat in front of you clear. If you can stretch your legs out, you will have an easier time with the Shell seat. However they do have a great AVOD system, so I stayed up a lot of the time watching movies that I haven't seen. On the return flight, I made sure I brought my own food.
