Any idea when this will be available to others besides your testers? It solves the main problem I had which was the Wand not working well. I considered buying a Flare but they seem to be out of stock everywhere and there's talk of a new model coming soon.
For any others that had trouble getting a hang of using the wand, check out Lee at TTB's technique -
He mentions that for the regular (non XL) Convector he puts it in for 7 seconds, can confirm that it works for me.
