I like how easy it is, so far everything works great! There are not many features but they do have some customisations which can be helpful if needed (such as adding an image).
It's free with no limitations or anything of this nature - just make sure what type/size file(s) will work best before using them otherwise there could potentially cause issues down-the line such as having too much space used up etc.. Easy set ups & tracking all campaigns across multiple channels including social media platforms eCPM performance metrics.
