I have to agree with the other reviews here. It feels dodgy putting this thing in the microwave, the plastic stand is very cheap (though to be fair, I get I'm only paying £6.50), but as others have said the rubber bung suffers in the microwave (it shrivels up) leaving all the crystals to go everywhere. As the bung is knackered, and there is nothing left to hold the crystals in, its basically useless. However, if you were careful, you could back in its stand upside down, but keep the hoover handy in case you knock it over. Basically move on, its rubbish really.
