@Lahey - I kinda applied the same screen approach. I removed the mouthpiece screen and white 'cermaic?' internal piece and used a tiny screen that fit perfectly in the oven. This increased air-flow and gave me a way to fill the oven 1/3rd of the way and keep the herb lightly packed for optimal heat soaking. I used the same approach on the Xmax.
@mulciber - I'm curious about the small white ceramic (Not sure if it is ceramic) cylinder as well. My guess is that:
- The screen and opening were small so the mesh on the screen couldn't be smaller or it would restrict flow too much.
- With the screen having slightly wider holes/mesh the cylinder was there to keep smaller particles and reclaim from going into the glass mouthpiece or your mouth.
- The cylinder also acts like a diffuser to smooth out the harshness/heat.
Did you noticed the vapor production is different with this unit, I would call it "non-linear"...let me to explain: I start at lower temp and got a huge first hit and others are smaller and smaller until I bump the temperature up, the same for each setting, one huge hit and decrease(it works like that if you start at higher t° too). I always got a thick first hit, even at low t° and considering the short heating time we can say the heater kick hard!
I'm mentioning some of this in my detailed review....I promise to post it up by tomorrow.....
I noticed the same thing about vapor production. I feel like the quick heat time versus ready to draw time can be a little deceiving on the Focus.
- The Xmax takes 100 seconds to reach oven temp on high. At the 100 second mark it is ready to produce because ..... it has been heat soaking the herb over a minute and 40 seconds while the oven reaches temp. In addition the Xmax air intakes are adjacent to the oven so some of the air will come in contact with the oven heat on the way in.
- The Focus reaches temp in a rapid 20-30 seconds but IMO requires another 15 seconds or so to finish a proper heat soak of the herb. The Focus air intake is under the oven and will not absorb as much oven heat on the way in as the Xmax. I'm not sure but the Focus intake holes coming into the bottom of the oven may also allow more air intake but not by much.
Conclusion: With the Xmax I get a steady vapor flow but the beginning of the hit is not as milky as the Focus. I enjoy using the Focus more like a cigarette in that the first mouth only puff is beautiful but diminishes the longer I draw. When I use the Focus with someone I've noticed that I get a much better hit if I wait 10 seconds or so after the last person has taken a hit before taking mine. I also noticed how easy it is to overload the Focus oven with my bubbler. IMO - with these types of cigar pen vaporizers moderating/slowing the draw to optimize the oven heat is the way to go if you want a long draw. Fortunately the Focus seems to have been engineered to optimize the form factor by allowing the intake to be slowed via the adjustable band around the air intake.
@druuna -
@mulciber: I charge the batteries in a Nitecore Intellicharger I2 and they are taking around 3 to 4 hours to complete a charge for what that's worth.
Picked up a focus as my first vape from PIU, charged battery overnight and ran 3-4 burn offs. Now the unit wont power on, it only flashes yellow 8 times when the battery is re-inserted. Any ideas?
Is your unit working ok now?
EDIT: Forgot to add the disclaimer....the difference in herb (dry or moist, difference in cure, etc.) along with personal differences in use can also change how a unit reacts when testing/used. Your mileage will vary.
it is not like it is out from few weeks ago. this performance for that money should me more popular., IMO. well, reliability also is a major factor to be tested jet. and when i test new vape i do it until she explodes. 
and a great effects as well. autoflowering strains come over 20% of THC these days. i guess i will have to order a few seeds of those modern plants. to crossbreed with my finest autoflower strains i cultivate for years now.
