Review on SanDisk Extreme CFast Memory Card by Pop Henneghan

Sandisk had a problem with old firmware and a new Canon 1DX Mark II. The problems have been fixed and I will be getting a new card from them soon . They were able to expedite the return of my $15 card, given that the media is needed now I'm happy to spend this rather than 2 weeks. I have sent several cards to Sandisk in 15 years and they have always replaced or upgraded the cards to a larger size for free; Your customer service is really great, there was only one issue with the 1DXII that made him suffer.
