Sure you using it right? My iolite has ALWAYS gotten me 3-4x higher than smoking the same amount. I grind up the weed and fill it fill to the cap (put the mouth piece in your mouth and suck bud into that chamber), then push it into the unit as its upside down so you don't spill (should hold .1-.2 gs). Let it heat up a few times before you start hitting it (most people say to give it 5 minutes but I don't think it needs that long myself), then hit it every 2 times it heats up (rule of thumb). Most bud lasts me 20 minutes, the good stuff I can vape for 30 min (although I guess I'm not sure if thats water vapor or THC vapor that late in the game). For me a pipe is 3 and iolite is a 9 or 10 (although for me personally its harsher on my throat than a pipe, still worth it as that feeling goes away pretty quick). You also need to use a good butane, one that is at least 3-4x filtered? There are a couple brands you are not supposed to use with them for some reason, maybe thats why it isn't getting hot enough for you? I'm using Mega Plus 5x and its working great for me.After using only the Iolite for the last 2 weeks, I decided to hit the glass pipe tonight. Fuck....I'm ripped...I'm about 1/3 of this with the Iolite.
The Iolite has it's place and so does the pipe.
If I was to compare the high from the Iolite vs the pipe:
If the pipe high is a 10, the Iolite would be a 4. IMO

I suppose there is also a chance you just got a bad unit (I doubt this though as I've only heard of it once or twice in the last few years), even though I doubt you bought from a seller who could legally sell the warranty (most who can sell an iolite set for $200), you could probably get a replacement from the North America base like I did (they upgraded my 1st gen iolite to a 2nd gen + spare parts for free and I had bought from the wrong seller!)
