I think that this hat should be around this price because the other unusual Katyusha's are higher than this price. The Coupe D'isaster which is a much lower tier hat is 1.2 buds with this effect and there are 10 more of them than these, The cheapest Katyusha which is 1.6 buds is green confetti, the Coupe D'isaster green confetti is priced at 15 keys, surely this means that green confetti is a lower tier effect than Kill-A-Watt, so Kill-A-Watt should cost more.
