Sure. They all are free for registration. Some may be of some nTLD's so it may be hard to register, but technically all are free.wait so all the domains are registerable right?
I bought this service the other day (not a review copy) and managed to get some pretty juicy deleted domains. Most of the domains weren't related to the keyword I gave him but it was a fairly spammy topic so I wasn't expecting miracles. Found several dozen TF 15-20 domains with clean link profiles. You'll need to be able to filter out the spammed domains on your own but overall its a great value service for building a pbn.
