I purchased an Arizer Solo 2 a few weeks ago and have used it heavily since then,
It has replaced my mighty as my daily driver and I'll compare the two in this post.
(The mighty is a beast and has a reputation so I won't go as far into that)
First off Solo 2 is smaller in size and has a much longer run time to mighty, I've been getting 16-10 min sessions at 185c with solo 2 and Maybe 7-8 8-10min sessions at 185c with mighty.
Draw resistance is much improved from their other units solo1/air
Some resistance but I actually like the amount and find it hits easier than I expected and only if you pack too tight do you notice and then you can lift stem a cm out and that eases the draw.
The glass stems are able to hold less but I fill them full (.15) and find I get huge and tasty draws which are comfortable on the throat for the whole ten mins. ABV is dark and even.
The glass stems it comes with are 90mm and 110mm. Both are nice, work well and come with a plastic carry case. It's comes with a carry case for the unit which holds two prepacked stems. I enjoy and use the carry case. They include silicone covers for the glass stems to pre load or to put away when hot. They are essential and I bought an extra 4 plus it came with 2.
The included stems are big and make the solo 2 feel less discrete but all the glass stems from all their products are interchangeable so I separately bought
2 70mm all glass stems (arizer air)
2 70mm tipped glass stems (arizer air)
I prefer the 70mm length for travel and stealth and find the 70mm all glass to be my all time favorite.
I own two small RYOT foil lined zipper pouches to carry the extra 70mm stems. Works great, reduces smell, is heat resistant for putting away hot glass, and gives padding for pockets. (1percent.com
The ease of cleaning the glass stems and total lack of ever having the clean the oven are my one of my favorite things.
The stems just soak in 95% ever clear,
91% ISO or 99% ISO if you can get it.
Hit it with a q tip, Rinse with hot water and dry. Very fast and easy compared to the mighty... but I clean the stems more often.
The mighty is harder to keep the oven clean (unless you use aluminum dosing capsules, I don't) and I will do 210c burn offs by a window and watch lots of vapor come pouring out of an empty unit. After a few mins it stops, so I know over time oils collect and you can not really get it clean...
The solo oven may get minor stains but should not really ever collect much as it's the glass which gets dirty.
The ease of loading the stems and taking a small space case or something like it with preground herb can provide many uses on the go.
Other users like to use whole buds or finger ripped bud and that works fine too.
I use stainless steel screens in the glass stems and prefer that. Puff it up has a great deal 50 for $4 and free shipping...
Also the 70mm stems :)
I make a small upward dome shape to the screens, keep the four air holes free and
Keeps particles and ground herb in place :)
Lastly the session timer lets you set from 5-15 mins and that works better for me then every min or so having to tell the mighty I'm still here.
Always more to say but another long post,
All in all very pleased! It's a great unit, takes some getting used too but not too big of a learning curve, especially for those already vape savvy
