I run a production environment with a few printers in a "printer farm" configuration.  We went through an extensive process evaluating filament vendors and their filament.  In the end, Sainsmart got the contract for our ABS needs.

We buy a lot of filament since our printers run 16/5.  Mostly blue, but we also have a product family that uses the "silver".

The Sainsmart filament continues to be an excellent value with good quality and consistency.  It extrudes well on our machines at 230C, and the filament diameter has been consistent enough that we haven't had to worry about recalibration or over/under extrusion.

If I had any complaint, it would be that the color isn't particularly consistent from reel to reel.  If we have to change reels mid-print it is usually easy to see where we went from one to the other.

Good stuff though... highly recommended.
