Hi Captain73
if the outside defects are under the glaze then the ceramic has had its final firing and all should be fine. They were probably bits of clay not brushed off after moulding and then fell off during the first firing leaving pock marks.
The ragged edges inside are also cosmetic and should not cause any problems, its poor quality control when cleaning the "green" clay after moulding and all mould lines are trimmed off.
But if you are unhappy with the appearance and lets face it despite being 40% the cost of a BGE or KamadoJoe this is still 350 quid you have spent, then you have the right to a replacement or money back.
Cheers
Jan
