I have had my Pax for about a month and thought I would share my experience with it.
I bought it used from Ebay, it was supposedly used as a review piece. I wanted one really bad, and they were all backordered, so I took a shot on a slightly used one, and man has it been a trip! It was advertised as 'mint' and 'just cleaned'. Suffice to say it was neither.
The temp change button was sticking, temp light coming on, sticking mouthpiece, all the same problems right from the box. So I remembered reading this thread and the fixes for all the issues and started working. I ended up using bread wrapper twist ties to clean around the spring area, and they work great. I had a friend give me a huge bag of them 20 years ago, and I loved them for cleaning a one hitter bat tube and bowl, so I thought I would try them for cleaning the tube and spring area.
I don't know of place to buy something like that, but they always worked better for cleaning one hitters than pipe cleaners did, IMO.
I am happy to say that all the issues have vanished and it is a perfect working unit now, and it is quickly becoming my favorite unit. I clean the spring area after every oven full and soak the mouthpiece once a week in 91 iso along with cleaning the inhalation tube and it works flawlessly. I usually clean it and stick it right back on the charger, giving the iso a chance to evaporate away.
I just recently clean my oven screen using the wire wheel on my shop grinder, and it turned out like new! The wheel took all the old, brown residue off and took it down to bright, shiny metal again. Cleaning the screen definitely helped with cloud production.
Even with all the problems I had getting all the crud out of this thing in the beginning, I am amazed at how much I like it. I think it hits as well as a Solo, both units set to maximum, and kind of reminds me of a large Bic lighter in my pocket, which I always loved the shape of a Bic, very 'hand friendly'.
I find myself using this more and more every day. My buds like it the best of all my vaporizers, I can get all of them coughing their lungs out with either one, but the size, shape and portability are real winners in mine and all my friends minds.
Personally, I don't find this to be a real maintenance issue. I take about 30 seconds to clean the spring area after every oven full (may be overkill, but paranoia has set in at this point), and a once a week soak for the mouthpiece is no big deal for the portability that it offers.
I have found the battery life to be very good, allowing me a whole days vaping away from the house with no issues, and still heats well while the battery charge is showing red.
I love making an oven kief sandwich, the clouds on high are devastating, you only need a couple of those for a nice head bake.
The only bad thing I have to say is that it lets off too much smell in your pocket. I use some pretty stanky medicine, and at my daughters wedding on Saturday I was in a small room with all the men, and started noticing a skunky reek coming from my pocket, so I excused myself, went to the car, took a few quick hits and left it out there. I am a auto tech, and have been looking for a couple of oblong, silicone caps to put over each end, which I was able to do with my Thermovape equipment and the stems for the Solo, but have not had much luck thus far in finding the right caps. Maybe a custom cap set from Ploom? It sure would help cut down on the stink.
For movie theaters and enclosed places, I still prefer the T1 or Evo. It is what I consider to be a true personal vaporizer, and offers the ability to do one hit and shut it off without a lot of waste, which I see as a problem for conduction style portable vapes. Convection is definitely the way to go, IMO, for keeping the smell to a minimum.
Overall, I love this vaporizer, it shows great engineering and a solid package that should stand the test of time. What really excites me is that the portable vaporizer market is still a pretty new concept, and I am sure I will be thrilled as new tech and fresh ideas come to light, I cannot image what we will be vaporizing with just 2 years down the road.
My best to all my friends here on Fuck Combustion! Have a vapey day!
