If it doesn't have a actual intake/exhaust (like a AMS Pro 2 or a Polymaker PolyDryer or a Creality SpacePi x4) then it's not worth any price. Proping open a dryer so it can vent and then having to seal it once it's done is a pain.

Anyone got experience with this specific listing? I can't see anything about the filament in the description other than the title. No review shows it either

at least one review on the site says they didn't get the 4 rolls of filament on this deal. seems a great deal if the filament does ship but, making the dryer ~$50, but a gamble if they don't ship the filament too
