Easy, effective, and inexpensive
on April 4, 2011
The Drymistat does its job exactly as it should. Other reviewers have more experience, so I defer to them for details of effectiveness. By the way, the thickness of the tube is ~the same as a cigar tube, and it is 5.5" in length. The instructions advise placing it in the center of the humidor.
There is perhaps some understandable confusion because the instructions could be written better, and that is why a few reviewers had problems with leaking: "Some evaporation may occur while sitting on the shelf. Remove wrapper. Add plain tap water to the Fill line. Put perforated cap on tube and wait for water to be absorbed. . . . A mixture of Propylene Glycol and water has been specially formulated and initially charged into the crystals."
When you receive the Drymistat, pop the cap and take out a crystal. You'll notice it is moist. This is the "initial charge" referred to, and the amount of moisture will depend upon, as the instructions say, how long the item has been sitting in inventory. The instructions mention that the tube has microscopic pores which permit moisture to pass thru; this is why there can be evaporation. All that's required is to add a small amount of water - if necessary - to the fill line and then leave the tube upright with the second perforated cap on, until that water is absorbed by the crystals, which is pretty quickly. Turn the tube upside down and gently shake it or very gently squeeze it, and any excess water will come out. Now place in humidor and there won't be any leaking. The crystals will shrink as the water transfers to your absorbent cigars or whatever. Refill when crystals shrink below the lower line on the tube. That's all there is to it.
