OK, I submitted my reviews on Amazon.com and I have to say bothe the ABS & PLA filaments worked great with my E3Dv6 hot-end and Felix 3.0 printer. The only thing I did notice is the PLA did give a plastic order when printing. Oddly the ABS had note much of a noticeable order when printing. Both time I did have the windows open because of the good weather. I definitely can recommend these Lexcent filaments. Thanks
