Derma rolling at home - Yay or Nay?

I know dermarolling at home is a very controversial topic. There are two camps to this, those like me who do it at home and really love the benefits of it without having to spend money at an esthetician and those that also believe that such treatments should only be carried out in their hands of professionals. I do my dermarolling weekly and the channels that it opens in my skin really allows for the full absorption of the key ingredients that I put on it after the procedure. I do see a difference in my skin doing this once a week. I feel it allows my skin to fully absorb whatever serum it needs at that point in time. Which camp do you belong to and why?
