Thanks for your thorough Youtube review on the EG a few weeks back. I've been quite astounded that no one has been concerned about the fault you encountered. As I understood the grinder just stopped working after a few grinds, until you fixed a bad solder on the "motherboard"? I find this quite alarming, hope no one else experiences this. Not everyone can fix it like you did :)
If someone doesn't know the review I'm talking about, it can be found here.
