Haven't seen these before. Seems very interesting!I pick the Easy Plugs
YepEz Cloner.
Or ,
I use 8oz plastic beer cups as a resevoir. get 2 x 6 ounce cups(usually sell them right beside the other beer cups), put a small drain hole in the bottom of 1, fill it with Black Gold seed starter. Put the other left over 6oz cup on top so it acts like a dome. Using this method normally my clones will droop a little in the first couple hours, and then will be standing up over night, which normally signals success for me.
