Filament Dryer Box for 3D Printer Parts Upgrade Airtight And Moisture-Resistant for 3D Filament Storages Keep Filaments Dry Boxs

I got exactly what I expected. I wish there were instructions for batteries or any indication of what type of battery there was. I used 2x 1.5v duracell 307/386 which seems to work with a little bit of a a folded piece of tape spacer, but I bet the same diameter battery that's a little thicker, as long as it's 1.5v a piece, should work better.

so far its great. should be better once I figure out what batteries the display takes. but its been great will be ordering a few more.

not used et. filament still packaged in factory protection.

Not bad. It seems to be the fastest among the recent orders I've placed on Ali. The packaging was also well done, which was a pleasant surprise.

The complete set has arrived

Ok.
