Keeps things dry
I like it overall. Much nicer than constantly resealing spools in plastic bags between use. Keeps the humidity around 11%. It is a bit awkward to wind the filament back onto the spool when unloading.

The Prusa USS Drybox is The One!
After years of trying different things and considering drybox options, the Prusa USS Drybox checks the boxes.
[✔️] Sealed,
[✔️] integrated hygrometer slot,
[✔️] side-loading (that's more important than you think),
[✔️] stackable,
[✔️] simple.
They aren't the cheapest, but they are far less expensive than my time trying to make a homemade version.
I see that another reviewer claims that only Prusament spools fit the box. I can attest that 3DFuel spools fit and work fine. I haven't tried other brands, yet.

Great Dryboxes
It was easy to order. PS informed me when the dry box was back in stock. Shipping was fast.
