The brushes got lost in the mail. And I haven't got my money back (yet maybe) :(.Ordered a brush set when there was a great sale plus free shipping. Brushes came rather quickly and didn't have any fees or issues... Those are part of 10 Sigma reviews. The latest review from Trustpilot - I placed 4 large purchases in one month, three had issues and two of those were missing items by bait-switch deals to which they had no intentions in fulfilling. Thank you Sigma. I see your true colors. All around gross mismanagement. Thank you, but no thank you. I'll take my business elsewhere. Oh, another thing I unsubscribed and somehow still received a "Come Back, we miss you" email offering 15% off on the next purchase. If you honored your deals, I would gladly be back. Keep your lies and dishonest apologies.. There are 2 excellent reviews. 1 of customers rate great. But there are almost 7 of people rate bad.
