My Fez exploded when the battery went tits up. I shant be using that product again - there were glitches in the firmware (ie: repeatable defects in charging cycles - right where you don’t want to have problems) it just came across as cheaply built and poorly tested. Like there was a sudden spike in sales and they went with a new manufacturer…
I’ll be trying the Pax 2 next time I’m at bat.
Edit: Just to add there is a commercial for the Pax 2 in an episode of Broad City
