Hi Bill
Using leaf tobacco in the Iolite is more like pipe smoking than cigarette smoking. A small pinch of baccy will last about 10 minutes, then you want to empty it before your next session IMHO. For more throat hit and buzz you can add more than a pinch of baccy, but I haven't personally tried filling the bowl right up and leaving it in there for multiple vapes. It never occurred to me
The butane lasts one hour per ml so if you are using a 250ml can, that should last you 250 hours. However it does depend on the length of your sessions as the first 30 seconds after turn on it burns more butane than in the next 10 or 15 minutes. So lots of short sessions will mean the butane would last you half as long. But it is still a long time on a can. The unit holds 3.6ml and on average this lasts about 2.5 hours of constant vaping I would say before you have to refill the butane from the can. I work 11 hours per fay and one fill lasts me until I get home in the evening.
Whether it is as satisfyin is a personal thing. It is different to smoking but I find it more satisfying and comforting than an ecig. It is cheap to run, has a long warranty and tobacco is readily available everywhere. The vaped tobacco flavour is different to smoking, it is a more woody, almost chocolate taste. You can also experiment with flavoured pipe tobacco if you want to spice the flavour up a little.
Hope this helps
Andy
