1)Battery life.
2)Heating time
3)Ease of use
The battery life is now fantastic, with it's new lithium battery Arizer states up to 20 uses per charge.
This depends on a few things, such as the temperature it's set to and the time it's on, but from our testing it's so much better than anything Arizer has produced to date.
Excellent battery life!
The time it takes to heat up has also greatly improved, it's literally takes just 10 seconds to heat up to 220 Celsius which is the Solo-II highest heat setting.
The heating can be set to anything from air temperature to 220 Celsius, we set it at it's highest setting and it vaped without combusting the plant mater.
Although the glass mouth-piece that contains the botanticals actually touches the heating element within the Solo-II and it does heat up, the botanicals are insulated to an extent. .
The Solo-II relies upon the users inhalation to draw hot air through the plant matter to extract the vapour, sort of a convection style of heating.
As for ease of use, the Solo-II is a dream. It has a child-proof mechanism that requires the user to hold down two buttons simultaneously to start up.
This process takes 6 seconds and the new digital display lights up with a small smiley face when accomplished, happy days.
Once start-up is achieved you simply set the temperature as needed, too easy.
The size of the new Solo-II is also an improvement, perfect to slip into your pocket.
The only thing I wasn't keen on was the glass mouth-piece, I know glass provides the purest taste, but I prefer the screw-on pipe-like mouth-piece that fits better between the lips, so I changed the mouth-piece for personal preference.
So in summary;
No Burning or combustion of plant material.
Excellent battery life.
Super quick heat time.
Great terpene taste.
Very portable.
I love it!
