Very well built and worked as expected.. I liked it so much I purchased a second.

Overall, I think the S1 is a great product that solves a specific problem for my single color farm printers better than the alternatives (DIY or AMS). I love that it will work with any printer I have or can see myself using commercially in the near future.

Working on putting the S1 with 2 - 5kg rolls of filament in a tote and running it in there as a dry box.

Works perfect - great for large prints and using up partial rolls

Currently on my Bambu P1P but I have several P1's and 1 X1C

I am using the 3k S1 but love it already. Built very well.

The S1 is awesome, it makes loading filiment so much easier. The setup was easy and smooth. I would definitely buy again.

The filament was stuck on the spool and the S1 overcame the resistance without pausing the print. Kudos!
Buying another one.

Works perfectly, I can load any size filament up to 5kg spools and forget about runout.

Just what we needed- after some modifications to our Lab we are going to buy many many more.

No more standing around waiting for a filament change, no more layer gaps, just send it!

I think you’re created a really great product! So far no problems. Great to using up leftover filament.

Parts assembled beautifully. Now I can’t print huge models requiring 5-10 kg filament! Thanks guys!

Voron V0.2, TV06 after modifying the reverse bowden tube mounting.

A great way to use up those ends of filament. Or, you can snip off a couple of meters and do an inline color swap. Stripes!

The S1 works amazing! I don't have to worry about having half spools laying around. I love the fact that you don't have to change any firmware. My only critique would a longer power cord.
