I bought 3 crock pot lunch warmers with intention to make presents for my colleagues.The design looks good, color is nice,but inside is extremely small for a lunch size portion,maybe even for little kids. But plus the cover,the food warmer nearly cannot fit any lunch bags. After plugging in,the warmer takes so long to warm up,so is there any reason to bring it to the office when they already have the microwave there? So I cannot use the food warmer at the office,nor outdoor picnic or travelling.Not a good experience in purchase.
