Just got my iSpire yesterday afternoon. BTW, kudos to VGoodiez on the delivery...I ordered around noon on Saturday and I had the goods in hand (STL area) by midday Monday.
With the DV, I'm using a 2019 Vong stem with a Stinger and 2020M tip/cap on a bong. I've done about a dozen bowls, most of them CBD. I'm getting a click every time. It usually takes more than 10 seconds for the first one, but when it clicks, the DV is immediately ready to produce good vapor, and usually two better-than-decent hits. No need for a dry click with the iSpire. I'm clearing a bowl in two heat cycles, with very dark brown AVB.
I think what's happening here is that the iSpire chamber is deep, so if you have the tip of the cap even with the top of the iSpire, there is heat being applied to the spade area of the cap and the cooling fins. That's not an area that most IHs hit, nor is it where most of us would aim a flame if we're using a torch. So, the heat mass for the Dynavap with iSpire heating is coming from a significantly larger volume than what you would normally get -- you're actually heating what is supposed to be the first line of cooling defense! Net result is big-time cloud potential. I think the combustion risk is higher; I've not crossed the line yet, but the margin of error here seems smaller.
But I love the payoff.
I've done a lot of reading on the iSpire, so somewhere I read that the temperature control is not really relevant when the wand is being used to heat a Dynavap and that the only thing that matters is the click. Is there any consensus about that?
I've done two concentrate runs and both were very good. Probably not as good as the RiO, but not having to deal with a torch is a big plus. Only issue with the iSpire here is that I'm getting remains at the bottom of the cups and no combination of Dark Crystal or iso is making a dent, even when warm. I'm starting at 500F and bumping up to 550F to finish. Anyone else seeing something similar?
I readily cop to the fact that I'm relatively new to dabbing, but I haven't had this issue with either my RiO or Boost Evo.
