Love to compare the two but I'll need some time to test. As you may know, I LOVE the gh, it's simply instant satisfaction but after doing 3 loads with the MiVape, I'm beginning to love this vape too. They are quite different but both share some of the most important features in my book, convection or mostly convection, replaceable battery, fast heat up, fun, etc. I hope to have more information for you all later next week but I have to say that I am very happy so far with the MiVape, it tastes great and its fun to use and lots more. I would honestly spring for both of you can because they both offer different things and one may be better for one thing than the other
Not to mention the mouthpiece assembly where the vapor briefly passes through some plastic of the rotating draw stem and I think there is a tiny portion of silicone tube at the air intake at the bottom that connects to the glass heater tube/spiral. The MiVape is by far mostly glass, especially in the important areas but their is also plastic, the mentioned SS screen and possibly silicone. I would call it pretty much all glass, the pieces that arent, don't amount to much.
For sure, gotta do some more testing and they are both great so far, just different....and your absolutely right, that a little goes a long way with the MiVape, geez, I got like 10-20 draws off of hardly a pinch! but I did have it on a low temp
