I like them.
And yes, I must admit I am a bit of a detractor of OG 28s - just had too many duff figures off them I'm afraid.
But maybe 10mm is their strength, because these look great. 
The effect en-masse is superb and I'm looking forward to see the whole regiment fielded.
I have quite a few OG15s Napoleonic and ACW figures and they really are quite good. Not up to AB standards, but as good as most other decent ranges in this scale. I think it must just be the 28mm stuff that suffers from the wildly variable quality.
