Has anyone tried these products for Humidity?

[Becca]

Okay....two products I saw.....one I am not that interested in, but thought I would still mention it.
The first one one I would think do the same as a sponge, although sponges aren't quite getting the humidity to where I want it in my orchidarium, which is around 70-80%. It hovers around 60-65 percent, sometimes in the upper 50% area:
:Reptile Humidimat Terrarium Humidifier 15"x4" - (eBay item 200040763229 end time Nov-19-07 13:32:26 PST)

The second product I am thinking of purchasing a few of, two for my large orchidarium, and one for the small one, although I am still trying to figure out of I will run cords out of the top of my Exo-Terra if I put a piece of glass over the top to help keep humidity in, and some of the heat out from the T5 lights, which I am receiving today!
Anyways, here is the link: Tropic-Aire Terrarium Humidifier and Air Exchanger Small Pet Products

Reptile Terrarium Humidifier, Tropic Aire Humidifier ( No Pump )

If anyone has any experience with these products, mainly the second one, I would really really like to hear how they work as I think I am going to order a few. Any other idea's are welcome! TIA!
