After a few weeks of testing, I've come to 2 conclusions:
1) my shirts aren't as perfect as the starched shirts worn by waiters in a Michelin-starred restaurant (but who needs that kind of perfection?);
2) even if I forget my shirts in the machine after it's been running, they come out wrinkled.
As a result, the perfection/effort ratio is very high and close to infinity. I get nothing but compliments. Thank you, BF!
