There are several of these repair cafes around town where I live. My old Braun blender from the 70s that I got from my grandma got repaired in one of these. I sent an email with brand, model and photo when I registered, the guy got some spare parts on eBay just in time for the day and I managed to repair the blender under the guy’s guidance. Paid for the spare part (5 bucks) plus left 10 bucks as small donation. My blender is as good as new. Overall a great experience, would recommend.
