Example Input: I bought these in Sep. and these racks burned and melted on the bacon. So you will have to throw away the food you have cooked and the racks. I cook bacon maybe 3 times a week. Do not waste your money
Example Output: negative

Example Input: very disappointing product! In less than a year its doesn't work properly! After 40min of use it turns off, no matter if charged or no! Wouldn't buy again
Example Output: negative

Example Input: Please read before buying. No installation directions included with purchase. The provided clip fasteners do a terrible job attaching. After three rooms were flooded due to this bad fit, I reattached the hose with sealant and added a C-Clamp.
Example Output:
negative
