After testing GratKit's white PETG filament across multiple projects, I'm genuinely impressed. The first layer adhesion was buttery smooth—no glue stick needed on my textured PEI bed at 70°C. Unlike cheaper filaments, it didn’t warp or bubble even during a 12-hour print of functional brackets.

The toughness is no joke. I accidentally dropped a PETG-printed phone mount from my desk, and it bounced without cracking (something my PLA prototypes never survived). The matte white finish hides layer lines beautifully, giving prints a premium look.

Printing at 235°C with 30% fan worked flawlessly on my Ender 3 V2. Zero stringing on detailed miniatures, though one user reported nozzle clogs—possibly from insufficient drying? The included resealable bag with desiccant is a lifesaver for humid climates.

Minor gripe: The spool’s cardboard core feels flimsy compared to premium brands. At this price point though, the mechanical properties rival filaments costing twice as much. Perfect for durable prototypes or outdoor-use items.
