I have finally received my Caldron! Personally it is the only way that allows me to use a Vapcap M having results. I cannot easily use lighters and alcohol lamps because of my hands and therefore this Caldron gave life to the Vapcap M 2020 that otherwise would have remained in a drawer. I am very very very satisfied with the Caldron but let's start with the only cons: shipping. When I wrote: 'I finally got the Caldron!' it is because the journey of this heater from Canada to Florida and then from Florida to Italy was endless. Living in Europe, I wanted to have a complete shipment tracking, right up to my address. Pipes does not offer tracked shipping for non-Canadian and US mailings and so I wanted to use one of these services that receive packages for you and then forward them to your address. The extreme slowness, however, is related only to the shipment from Canada to Florida, the shipment of the Canadian Post Office that Pipes used. I joined the waiting list on January 28, 2020. The next day (29th), very fast, Pipes had already brought the Caldron to the post office in Oshawa, Ontario. The package remained in Canada, with the Canadian Post, until at least the end of February, before being passed to USPS in Stamford CT and then delivered to Sarasota FL on March 6th. Considering the cost of shipping this is a biblical waiting time. The package then reached my home on March 25th, a second part of shipment with acceptable times (considering customs approval). Here, the shipping part is really the only negative point of buying a Caldron. I hope Pipes will consider different delivery options in the future. But let's go back to using Caldron: in these 2 weeks I had the opportunity to use it a lot and I find it perfect. The learning curve is quite fast. Inevitably a lot depends on the quality of the strain, on whether it is fine grinded or not, on the humidity of the material and the environment, etc. I think (vapcap+caldron) is the most similar experience to smoking, also for the fact that it simulates the same gesture by bringing a small cylinder to the mouth but above all for the fact that you can also make shorter satisfying puffs. The puff technique changes a lot from most of the vaporizers I tried, which instead require usually very slow and long hits. The ideal now would be to use it with a vapcap with some glass parts instead of metal. A mixture of vapcap and biovapo. The purchase of the Caldron was a real success and the endless wait was still worth it. I recommend it without a doubt to everyone and especially to those who have a dynavap product and cannot fully exploit it with a flame heat source.
