Cigars are somewhat expensive and I want to take care of them. Long term, with no additional means of maintaining humidity levels they will loose the oils and flavor. I don't have an scientific explanation for why they dry out in a sealed container. Other folks here can probably explain the science of tobacco fermentation better than I can.
Somewhere after I'd filled my second wineador I realized that they were not probably the solution to my cigar storage. Now ideally I would have loved a walk-in but my wife did not. The irony is I have probably taken up the space of a walk-in humidor with other storage options, not only that, the walk-in would have looked a hell of a lot nicer. I have also managed to get a grip on my CAD in recent years, partially due to TAD but I've come to the realization I may never consume all my tobacco. I admit to having a compulsive personality when it comes to these hobbies, I'm somewhat embarrassed by this quite truthfully. I am not bragging here, it just happened over the years. I love having choices too, and boy, do I have choices.
I've been using plastic storage for a long time, years in fact, with no problems whatsoever. Combine totes with Bovida and in my experience it's the most care free storage I've ever had. I dare say it's probably less stress and effort of having a walk-in humidor. The other thing is it's economical beyond most other options. I am usually in them enough to inspect cigar stock for problems and make a point to inspect them all probably twice a year.
Don't take my word for it. This link is exactly the product I've been using a long time. Halfwheel reviewed them in July and I imagine these guys have some cigars that need stored. Ultimately as hoosier pointed out, they are your smokes, enjoy them.
At a certain point—probably around 300 cigars—people will begin to realize that storing cigars in desktop humidors is not very efficient. Desktop humidors
