I bought the Bistro coffee grinder and it's never worked properly since I've had it. Mine clogs before a single espresso's worth is ground and sent them a video showing the issue. I complained to Bodum and they said it's not a manufacturing issue and due to static. My son's Delonghi is excellent. I've wasted £50. They didn't get back to me from the chat bot on their website after I did all it asked for and I had to scour the internet for a phone number.
