breathing color crystalline

Dear fellow printmakers:
For a short time, BreathingColor made their crystalline canvas a available.
As soon as it ran out of stock months ago, it has been unavailable.
Yet, it is still on their website ( but out-of-stock ).

Does anyone know what happened?

I had an opportunity to test the product. It saved me a lot of time and produced supersharp landscapes.

The only shortcoming seemed to be "curl".

Does anyone have an inside on what happened?
I have this feeling there was some kind of problem?

And lastly, how does it compare to the epson exhibition canvas gloss and satin?

Any information would kindly be appreciated.
Regards,
MH
