I own a MFLB. I received my Arizer Solo 2 days ago in the mail and has been vaping my $50 per half oz. Master Kush with the Solo since. My MFLB is currently underneath my bed.
The construction of the Solo is amazing, it feels sturdy, and has a great weight to it. It feels very well-made, not some cheap plastic crap made from oversea. The quality of the vapour is amazing, I get the cloudy effect that I couldn't get with the MFLB. On top of that, the heating chamber appears to be very easy to clean and barely gets dirty at all. The battery life is incredible (coming from a MFLB), I can vape at least 5x longer on the Solo without having to charge/swap battery. I also love the fact that I can use e-cig oil (not that I will), and concentrates as well. I believe it works with shatter and budder? (correct me if I am wrong).
This is one Canadian product that I am extremely proud of (can't believe it's assembled in my country), and would buy again from Puffitup.com
Considering that it's a Canadian made product, I think it's f*cked up that it cost way cheaper in the states than it does in Canada. Lol
Happy Vaping guys!
