TheStreet Ratings team rates INFOSONICS CORP as a Sell with a ratings score of D+. TheStreet Ratings Team has this to say about their recommendation:

"We rate INFOSONICS CORP (IFON) a SELL. This is driven by a number of negative factors, which we believe should have a greater impact than any strengths, and could make it more difficult for investors to achieve positive results compared to most of the stocks we cover. The company's weaknesses can be seen in multiple areas, such as its unimpressive growth in net income and poor profit margins."
