Update on my chinese inductor experience:
I have made almost the same tweak
@Pablo-Diablo did in order to make it heat more evenly.
Dismounted the board and tried some cap positions for best performance. In my case i was not satisfied just placing the vapcap deeper. It was still hotspotting because the way the coil is bent makes it concentrate heat narrowly.
I made the coil wider by separating it with a screwdriver very carefully from the top part of the glass to the bottom so it heats a wider area. For this operation I had to cut the bottom silicone to my perfect height and reshape the frontal silicone ring with a knife to make place for the taller coil.
Now I can get exactly the performance i want from an induction heater, specifically adjusted for my personal preferences. It clicks at 11/12 second from cold (I have to reinsert the vapcap mid heating) and about 8/9 seconds if it is a reheat, but now it heats evenly to a high temperature and the clic works as expected, no more bliking light counting and no hotspotting at all.
I fully extract in 2 or 3 heating cycles leaving the herbs almost black, no hotspotting and very dense vapor.
As expected with this modification battery life has gone downhill and now sits about 18/20 clics per charge, which is still pretty good in my opinion. And I better get 20 good hits than 50 whispy ones.
So final thoughts: This CAN be an extremely good budget induction heater if you modify it, but if you aren´t going to modify it and like dense clouds better pick another option. I think the orion is slightly better than this one but it still is lacking an even heating. If you feel adventurous and customize the heating experience like i did, Go for it!! It can be a great induction heater, much better than any portable one!
