Combined with the FitVids for WordPress plugin, this playlist player has a very nice look and is fairly easy to configure. But this is only for desktop viewing, for mobile it does not work.
I have written an extensive report about the testing that I did with this plugin in the support area, so I will not belabor the facts here. I will just say that the claim in the description that support for mobile devices has been added is not accurate. What they have done is to use scripted code that diverts to a special YouTube playlist when the player is clicked; and on the vast majority of mobile devices, that playlist will not play.
