I got the new Wand's adapter and I don't like it. While it is simple and fits snuggly the Wand, the taste of the draw does not satisfy me. I find it better heat the cap directly, placing the wand upside down, so the cap sits at the rim of the glass cylinder. Heats evenly. With the new adapter, the result is similar to the 1st gen carbon adapter (with the orange plugs) : dark brown outside and light brown at the center of the load.
Also half of the times the cap stucks inside the adapter. I suppose it is large, so while it fits tightly, it is too tight actually and the cap stays inside, as I am removing the DV, leaving the tip naked. If the adapter is not inserted into the wand, it is easy to remove the DV, without cap getting stuck.
Have they even tested it with a captive cap? Not extensively I guess. It needs redesign.
