I have a couple I’ve been running for about a week with ABS and HIPS.

PLA seems to be the most problematic, though thats only going by online discussions.

I would strongly suggest making a good fan duct to blow on the fins rather than the odd fin they recommend.

I forgot to add, its been working very well for me. But I don’t have more than 60 hours of run time on them yet.

I might opt for those instead of E3D for my Herculien build.

I’d post a photo of my Pico setup to this thread but G+ isn’t letting me.
