The Arizer Solo II is a great improvement from the original version. It offers incremental heat adjustments on a digital display. Another improvement is the airflow through the device has improved significantly. The shipping was less than 2 days and the price was very reasonable.
This is my partner's third Solo purchase with each lasting over 3 years. Just as happy with #3.
The Arizer Solo is an excellent vaporizer for both new and seasoned vape connoisseurs. Very easy to use and always produces tons of vapor. Glass pathway is absolute best, and allows for the taste of the product as well. Cannot go wrong with this device!!!
