1. Production: Because many details of Toastrus mini are handled by hand and high-precision sensing technology is adopted, its production cost is high, so its production capacity is small.
2. Fame: because of its popularity in the market, its sales volume is large and its supply exceeds demand, so it is difficult to meet the market demand.
3. Supply chain problem: Due to the rising production and transportation costs in the supply chain and the influence of COVID-19, manufacturers in some areas were forced to stop production, which affected the output.
