"works great but took a while"
I would use them again. Worked great never had an issue with humidity since. I would recommend buying one for every 25 cigars of capacity. I got one for every 50 and it took over two weeks to get it up to 80*. I also dont think you have to wait to get it to 84 once it hit 80 and was there for 2 solid days I took them out put in 3 72* packs and added the cigars at once and it dropped to 73* and hasnt moved since.
