How many different customers have been supplied with Betas?

As to those Betas that have been shipped, are they working as expected so far?  Have there been some issues requiring some adjustments by Poet?  

Poet obviously knows all of the above. Do we expect a detailed report?  Suppose they announced that 5 of 6 customers required adjustments that Poet is currently working to remedy?  

But what we don't know is that when betas of any new product are shipped, maybe the norm is that 9 of 10 come back for tweaks?
