I have the 21-Gun Winchester Gun Safe...I currently have the silicia bead packs but wanted to also add a de-humidifier...I'm looking at the "Eva-Dry 500"  OR  the De-humidifier Rod...Which one do you guys prefer?  I'm liking the Eva-Dry better, but just hoping you guys OR girls could point me in a good direction based off your experience.  Thanks  Hope nobody complains too much about this question being in this category, but I don't where else to ask it.

I have the Eva-Dry 500 in my gun safe. Works great. In my ammo safe I use Wallyworld cloths closet dessicant cans. Happy with both.

The Eva-Dry actually absorbs the moisture whereas the rods heat the air which makes the air retain more moisture without depositing it on the guns. Either will work, you just gotta recharge the Eva-Dry every so often.
