You would think given the form factor that that the Kanso would have the stronger magnets. Unfortunately I can’t help much, I opted for the N7 myself, we did have a thread last week that seems to indicate that the Kanso 2 or whatever they name it is working its way through the approval process. Looks like it might be quite an upgrade. Unfortunately there was no time frame that could be found, and with CORVID any schedule there was is probably out the window now.
Hang in there it took a bit over two months for all of my swelling to go down so this may still work.
