My biggest issue is with the lever. I have to push it down between 5 and 10 times before it will trigger, without fail. I've had this across most all toasters I've owned.
My second biggest issue is related to the same mechanism: the "pop" is impotent and does nothing to eject what's being toasted. The most I can hope for is that I can manually push the lever up.
The next biggest issue is with heating element distance. If there's anything that is wider than a slice of wonder bread it's going to get sizzled by the heating element. In the worst cases it causes smoke to be emitted for several runs afterwards.
