NO2 Vaporizer VS Iolite Vaporizer2

The Iolite Portable Vaporizer was introduced in 2008 by Oglesby & Butler. Less than 2 years later, the NO2 Portable Vaporizer was announced by Vapir.
First of all, I am not an expert on the Iolite Vaporizer. I don’t even own the Iolite. However, since friends have asked me which vaporizer I would recommend, I am still going to attempt a basic comparison:
Benefits of the Iolite Vaporizer
Small – Smaller than the NO2
Impressive 40 second heat up time
Holds a charge for 2 hours
Uses a flameless gas catalytic heater
Holds a temperature of 374° F / 190° C (accurate within 5° F)
Powered by butane
Refillable with additional butane
Choice of color – Black, Blue, Orange, etc.
Benefits of the NO2 Vaporizer
Internal rechargeable battery
Digital temperature display (accurate within 2°-5°)
Temperature memory
Battery charge level indicator
Auto shut off after 20 minutes – Saves battery life
Stainless steel encased pure brass heating element
Less than 2 minute heat up time
Small (larger than the Iolite)
Less expensive than the Iolite – Saves money
Verdict – Which Vaporizer?
Like I already mentioned, I don’t own the Iolite Vaporizer. Clearly, the Iolite and NO2 are both good portable …
