As some of my Family, friends, supporters, related Facebookers, some Head piers and others already know a month ago we were blessed with a new addition to our family of a baby girl.

As has been expected this has slowed down the Head pie review output somewhat, the backlog is at the usual size and I am concurrently working on several reviews while time permits.
Unboxings are all up to date.

The Head pie group on Facebook, the recently begun instagram account and memes are very much alive as they are easy to do on mobile whilst a baby sleeps on my chest.

I should be completing a few reviews in the near future and then cranking them our again as our new schedule gets more settled and into routine.

Thank you for your continued support.

Kind regards
