Wow watch out, As a person whose fallen into that trap I must warn you...

I have ordered two humidors from eBay and I must say I'm thoroughly dissapointed. I got my first one, which I have kept until now, I noticed it was imparting a huge organic/spice flavor to cigars it was god awful I got my third humidor today from a JR retailer.
My first one, solid contruction but not spanish cedar..

The wood was definitely not 'spanish cedar' as advertised I physically noticed the flavor of my cigars warping in the matter of two weeks for lighter smokes and a month at most for heavier ones.

Then I bought this peice of junk: The plexi glass is is held on with four screws and doesn't even come close to humidity requirements.

While I cannot vouch for either the companies making the claim my experience has shown it to be completely true.

After all this I spent basically 150 bucks on humidors, one from JR - Hopefully decent, one for dog rockets to be gifted to college freshman I hate, and one that can be thrown away as its absolute trash... Let my bad judgement be a warning for you guys,,,, watch out...
