I just wanted to write a quick email to tell you how much I am enjoying your product.
I found the copper based filament I got from you to be so easy to use and without issue from the very first print I tried. I was initially worried that it would be hard to get good results or difficult to print correctly. Nothing could be further from the truth, it prints easy and smoothly on my Prusa i3 mk2 without any funny setup issues or special problems I have experienced with other specialty filaments.
Thanks for a great product.
My one request would be to offer larger spools so that changing out mid project would not be required on larger prints.
Thanks again, very satisfied.
