The Iolite is one of my favorite vaporizer. Its been there for me when i needed it most. The main thing that saved me was that its butane driven. meaning it doesn't have a battery. So one time i was using it when i was snowboarding. It stopped working and i was 3 hrs away from my cabin. I remembered that i had a can of butane in my bag. I had forgot, i was actually prepared. All I keep thinking about was that if i had other vaporizers. I would have been out of luck. The fact that it uses butane is great for cabin, snowboarding and any place that doesnt have electricity. I give the Iolite 5 stars.
