Comment on "Room Temperature Electrically Injected Polariton Laser"

In this Comment I challenge the main conclusions of Ref. [1]. The main reason for this Comment is the large number of questions on the details of the experiment that led me to request the raw data. I have obtained two sets of raw data. After a long discussion with the authors and the editors of PRL we decided that I should use the second set of data. Within the limited space of a Comment, I will only discuss here two of the published figures.
