Just had the first couple sessions with my new Solo. GREAT vape. Really impressed. Feels solid, hits very well, and seems extremely easy to clean and maintain. Finally I can sit outside on my balcony and enjoy some nice vapor hits.
It's funny, I saw the vapor coming through the tube, but it didn't register with me in the same way as it does with my PD because the vapor is so much cooler. Usually I can feel how much vapor I'm getting because of the heat, but with the Solo I don't realize how much I'm taking in. I think I forgot that vapor could be cool - I've been using my PD for a while, and it runs pretty hot.
No restrictive air flow issues at all. Maybe it's because I'm used to my PD, but the air flows on the Solo much more freely than it does, for me, on the PD. All I did was put a screen into the stem, domed outwards from the 4 holes.
It was also great to see the herb browned evenly with no charring. Even when I turned it to 7 to test it, the herb came out a nice and even dark brown.
So far, no complaints at all except for the awkward design of the power cord having to be plugged in on the bottom. I'd love to have a dock for this.
