In combination with aluminum powder results were better than store bought. No need to grind as indicated by some reviews.
Works great. Bought from them a year ago and it had a bit of debris in it. Did not affect quality at all.
This batch is very clean and I expect will work great.
this was priced right, quick shipping, worked great. Will be ordering again real soon.
