Negative Positive
Title: Only worked for 6 months...
Review: This frother was amazing for the first 4-5 months. Then it became increasingly unstable. It would work only if I held down the battery cover very firmly. Then after using it for only 7 months, it stopped working. I tried to email the manufacturer but the email address on my guarantee is not valid. I am very disappointed.
Is the review positive or negative?
