Sandisk CF cards issues with NanoFlash recorder?

Hi, I am in the market for CF cards to use with the NanoFlash recorder, however I noticed this message on the manufacturer’s website:

“PLEASE NOTE: We no longer recommend use of SanDisk Extreme and SanDisk ExtremePro.”

I have read reports from earlier this year that this is because of changes in the parts used to made SanDisk cards, which has caused multiple instances of card failure in the field when used with this device.

I was wondering if this is a known issue with you and if there is any further information available? Hoping the issue has been resolved?

Thank you!
