I will throw my vote in for the Arizer Solo. It fits my needs really well. I have the newer M1A version with the stainless oven. With the right accessories it's hard to beat for a portable unless you require stealth.
Portability: 8/10
It's definitely portable. At home or on the go it gets the job done. Do be careful with the glass stems.
Stealth: 3/10
It's not very stealthy on its own. There are some things you can do to increase stealthiness while in use but it's not inherently stealthy.
Battery Life: 7/10
Acceptable but has room for improvement. I can get 5 full cycles on a charge. I always keep it charged up in case I need it on the go.
Temperature Control: 8/10
It's nice to be able to select variable temperatures. I think the max temperature and battery life strike a fair balance.
Vapor Production: 9/10
Typically 3 to 5 dense vapor draws with an additional 3 to 5 lighter draws (a couple before and after the dense draws hit). Strain dependent of course. 6 to 10 draws is pretty good for the little bowl.
Flavor: 10/10
If anything will turn you into a vape snob it's the Solo. The flavor you can dial in with this thing is simply amazing. From light and fresh to heavy and hashy. Just the taste of your herb will bring a smile to your face not to mention the effects.
Bowl Size: 7/10
As the name suggests, the Solo will typically satisfy a single user session nicely and probably not more than two simultaneous users unless you are using multiple stems. The bowl is on the small side but for me one bowl gets the job done perfectly. It makes it easy to ration or dose with a consistent amount.
Accessories: 8/10
There are some great OEM and aftermarket accessories for the Solo that can enhance the experience.
- Power Unit - Saves battery life by powering the unit while in use. Does not charge though.
- Car Charger - Charging on the go.
- O-Ring Seal - Tighter stem fit.
- Bong Attachments - Fer yer bong
- Bowl Screens - Keeps the stem tidy longer and can also modify the bowl size (smaller still)
- Travel Tubes - Protect your stems and pre-load for on the go.
If portability outweighs your stealth needs seriously consider the Arizer Solo. At a base price of $160 for the M1A models you can get up and vaping with impecable flavor at a pretty fair price. Mine has been in service for over a year and still works flawlessly.
Cheers!
