Got my Solo yesterday and had some sessions with it last night...I have to say this thing put me on my butt. I was not expecting that. I went from combusting two good sized bowls in one sitting to get really medicated, to taking 3 hits on level 4 on the Solo and feeling similar effects but even smoother, and on top of that AMAZING TASTE every hit!!!
I worry a little bit about how loose the glass adapters are..neither are tight fitting and have a nice wobble when in place. I noticed that when turned on (level 4 after a few hits) it gets worse, the hook adapter actually swivels around freely 360 degrees if I tilt the unit in my hand around. At one point I was laying in bed and bringing the Solo to my mouth was kind of like trying to catch a bendy straw in a glass of water that gets away from you sometimes. Also, I noticed with both adapters, the loading part of the bottom where it meets the heating chamber would move up and down with ease. So while it's in my mouth, I actually am not sure as to where it is best seated...It can sit really far down and I have kind of bad airflow, or hold it up a bit via grip of my lips and get better airflow. I am not actually sure which is the correct way as it seems to just freely move about so much. It really is like drinking out of a straw and the solo is your cup, the heating chamber is that last bit of water you are trying to sip out between cubes of ice. I don't have a better way to explain it!
I bought my unit on eBay from a top rated seller. In their description they claimed to have the latest models being shipped to them every two weeks. In the description they also claim that their units boast the latest features like better airflow and being able to use while charging. Then I open up the instructions that came with the unit I received and it states something like "This unit can not be used while charging, you need to get a different charger for that". So I wonder.
I really really like the Solo, I was especially delighted at the size and ease of use, as well as instant and powerful effect with little herb. It's just the straw effect that kinda makes me feel a bit off about it.
Maybe all that I have stated is completely normal and I am just griping
