Just received my Solo from amazon, truly shipped in one day. I received a m107 even though the seller said it was m106, sweet! With amazon prime it is only $4 extra for One Day Shipping, making the total price $140. That is less than half the price of MSRP. The quality of this unit is better than i expected, it has a solid feel to it. Aluminum case instead of plastic. The unit is also smaller than I expected, it can really fit in your pocket.
When i unboxed the product, it was at charge level 3. I plugged it in to charge and I took a shower. Now it is at level 7 with a blinking green light (which indicates it is almost done charging I believe?). This thing charges super quick which is necessary since the unit cannot be turned on while charging.
I have not even turned on my unit yet, but I smelled inside the heat chamber. It is that classic printed circuit boat/electronics smell. Exact same smell my new PS3 slim gave off for the first few days of using it.
I will post up in a week or two after I use the unit more to give a mini review. I have used the Arizer extreme 2.0 for four years, that unit has seen EXTREME usage (taken to parties, taken on boats, car rides, etc). I am looking forward to seeing if I can achieve full extraction with 4 holes in the stem with not one screen (extreme vape has two screens).
