After a few weeks of using it, I got to grips with the Proxy... and the concentrates!
The silicone smell has lessened (and/or I've gotten used to it).
The “robot fart” smell/taste is no longer present.
And after long weeks in the open air, the case hardly smells anymore.
I probably add a little more concentrate, but I start at lower temperatures. Before I started in green or red. Now I start in blue or green. In all cases I end up with red.
It's a cool device.
Loading is easy and cleaning is awesome!
The battery doesn't last very long but charging is super fast!
Maybe I could have done without stepping foot into the world of concentrates...but I'll revise my judgment once I've purchased some higher quality concentrates.
In any case, I do not regret having started my experience with this vaporizer there. Once I get over my silicone sensitivity issues, I find that it's a great device to start with... or keep things simple!!
Thanks to whoever recommended it to me!!
