Works great for small and large rolls, I have this on a shelf next to the printer and it's so easy to swap rolls. Only complaint is a 1/4 full 1kg roll with a 1mm nozzle pulls a bit to hard and knocks it off. But I rarely use 1mm so not a huge problem

I put a 1kg roll of filament (18mm wider than Atomic's 1kg roll) and mid print, the printer caused the rollers to slip, sending my roll crashing onto the floor exploding into a huge pile of spaghetti. I contacted Atomic and they said its better for 3.5kg than 1kg, even though the website says 1kg works fine. Thumbs down.

Extremely good quality rolls like a dream with the huge 3.5 kg roll saved my life cause I kept wasting filament trying to get the old stand to work with it
