TheStreet Ratings team rates TASER INTERNATIONAL INC as a Buy with a ratings score of B. TheStreet Ratings Team has this to say about their recommendation:

"We rate TASER INTERNATIONAL INC (TASR) a BUY. This is driven by a few notable strengths, which we believe should have a greater impact than any weaknesses, and should give investors a better performance opportunity than most stocks we cover. The company's strengths can be seen in multiple areas, such as its robust revenue growth, largely solid financial position with reasonable debt levels by most measures, expanding profit margins, good cash flow from operations and impressive record of earnings per share growth. We feel these strengths outweigh the fact that the company has had somewhat disappointing return on equity."
