I didn't even know that there was such a thing.   I've only done it old-school with a steel bowl, double boiler, yolks and a ton of whisking.
Is the 30-sec variety any good?

	Oh yeah , you can't tell the difference. Heat up the butter and lemon juice in the microwave and then whisk in three egg yolks and your choice of seasonings. Heat for 5 seconds after in increments till desires texture. :D
