★★★★★
I've printed through several spools of SUNLU PLA and the consistency has been reliable, no tangles and minimal stringing on my prints. Great value compared to the pricier brands I tried first.

★★★★☆
The filament dryer box has been a game changer for my PETG prints, no more moisture-related bubbling. Wish the display had a couple more temperature presets, but overall solid.

★★★☆☆
Most spools have printed well, but I did get one PLA spool that had noticeably more brittleness than my previous orders.
