At present, "Changdi" and "Midea" are both good; this can be seen from the sales volume on Taobao.
As for the two issues that should be paid attention to when purchasing:
1) The capacity cannot be too small, generally 25 liters to 35 liters is more suitable
2 ) Power: 25L is generally around 1200~1500W; 35L is around 1500~2000W.
3) The temperature control setting range is between 80 and 250 degrees;
4) The upper and lower fire must be controlled separately;
5 ) has a timer of 1 to 60 minutes.
