I had over 25 system failures because the flashcards are corrupted. The ASC card is even worse. I no longer carry ESI and recommend all to look at other products with much more reliability. Someone posted that the Premise-based products are dead. I totally agree. ESI is focusing on cloud service which is ridiculously overpriced.I lost count on how many key employees ESI has lost within the past 3 years. It's a sinking ship and I'd be surprised if they are still around within 5 years.
