Anyone Seem The New 'Their Finest Hour' Series Of DVD's?

I’m thinking about picking up a couple of the DVD’s in this series about The Battle of Britain, specifically the titles on aircraft of the BOB & the Spitfire pilot title.

According to the blurb on Amazon, the Spitfire Pilot DVD includes contributions from Charlie Brown.

Just wondered if anyone has seen these DVD’s & can comment on their quality?
