Been using the solo (black M106 2012 model) for a week now. Can advice it to everybody. Heat up time is good, mostly it will be heated up by the time I loaded the bowl.
I did add an extra screen to the bottom of the heating chamber as well as in the top of the bowl of the glass piece. The bottom one seemed to increase airflow a bit, and takes away most of my concern of AVB getting in the air holes of the unit. The top one in the glass bowl was necessary to stop particals from getting trough and into my mouth. Luckily I had read this thread completely before purchasing the solo so I already knew this would work.
Taste is superb, and vapor production is amazing. My herbs last lots longer and the effect is lot clearer in comparison to smoking. My typical bowl will be about .15 to .2g of herbs and will last me mostly for a good 7-8minutes of vaping. First hit, 15seconds in, is almost always without vapor, but man what a taste. This depends on if this is the first load or not. when the unit is heated up completely, for instance when I start a second session straigth after the first, it will produce vapor even with the first hit after being in the heating chamber for about 10seconds.
I used to own an i-olite, but the Solo literally blows that away when it comes to efficiency and taste. Battery life is huge, for me, I can use it during the day as much as I want and recharge during nighttime. Never ran out of power yet. And the unit does not even get warm after several back to back sessions. Now only thing to see is how long it lasts. And it does not produce any hissing sounds or anything like that.
And I have been using it on the go too. Funny how people have no clue when they see me walking by. Seeing it does produce visable and smelable(hihi) vapor, I would not advice doing this if you don't live in for instance the Netherlands :-)
So those are my two cents for now.
Any idea if it is possible to get the glass tube to fit it onto glasswork in Europe? I have seen them being mentioned in this thread but only from shops in the states.
So happy I found this forum, it really makes a huge difference in deciding what units to buy or not. And as so many, I am on the waiting list to get my Cloud, will be my first desktop model...
I am LOVING the Solo + Aqua Vape!! I can't wait to get the smaller AV in a few days. The larger one works great, and holds quite a bit of vapor inside once it gets going. It does take a few pulls to get the vapor to start filling it up, but once it's there...whoa baby! I am guessing the smaller one will just cut down on priming time, and travel a bit better. It does feel a little awkward with the larger one towering over the solo. None the less, this thing provides smoooooooth tasty vapor. 
then I 
. So long story short the Phantom is a horrible horrible horrible vaporizing unit. I did taste the brass heating element after about a month of use, or should I say attempted use. Even at the highest temp, it seemed like it always either got too hot and basically burned the herbs, or didn't get hot enough to have anywhere near the desired effect. the provided bags are sh** but I can figure out away around that if the actual vapor, or "smoke" sometimes was actually effective. It was actually the exact opposite. I found my self using much much more herbs and not getting any where near the desired effect that can be reached with half of the that amount being smoked out of any water piece. So after a year or so I have finally decided to make another attempt at switching over from smoking to vaporizing. I did a lot of research and decided to go with the Arizer Solo. I purchased it from Quality Vape on Amazon for 160.99 USD. It should arrive in two days. I hope I will be satisfied. I love Amazon so much, and I trust them even more. Quality Vape which shows up as NW Healthtek stated in their ad that it had the latest upgraded model with 2 year warranty. I hope that I receive the M107SS batch/model. I am not sure what to do if I recieve a different unit (m102,103,104,105,106). Should I keep it anyways what ever it is? Was the Solo a good Idea?
