Reddit reviews 3D Solutech Silver Metal 3D Printer PLA Filament 1.75MM Filament, Dimensional Accuracy +/- 0.03 mm, 2.2 LBS (1.0KG) - PLA175TCMS

Those couplers are trash and so is the PTFE tube they sent. They may work for a while but you'll want to swap them sooner rather than later. Here's a list of upgrades you'll probably want to do. You'll also want to look up a tutorial on how to upgrade your firmware so you can activate safety features (thermal runaway protection specifically). This also doesn't include a BLTouch or EZABL (auto bed levelers) as I have yet to make a choice personally.

AFAIK, the silver PLA that came with my MK3S kit isn't official prusament filament (no QR code, no prusament branding, not a prusament spool), though I have no complaints about it.

I do have a few spools of official prusament, and I have zero issues printing with them. Very smooth flat walls, oozing is controlled (no stringing), and the built-in Slic3r PE profiles for prusament are spot on. I like that the filament comes with resealable bags to keep the spool in with the moisture absorbing pack, as well as the honeycomb spool it comes on. The QR code to see the stats of the filament is nice, but kinda gimmicky, and doesn't impress me any more.

All that being said, I'm currently printing with some 3D Solutech stuff I got from amazon for $16 which claims +/- 0.03mm tolerance and again, it's wonderful quality while printing. It's not wound on the spool nearly as nice, though.

I may do that. I bought this filament hoping that it would appear metallic. It prints nicely but it just came out as a dull grey.
