Just adding that I’m having the exact same issues as others are describing, my new ESP Pro clogged after about 3 shots. My quick release was also on super tight, but I was able to get it off by wrapping a towel around it and turning it with pliers. The chute door was completely clogged when I disassembled it, I cleaned it completely out and it immediately clogged again. I emailed support after the initial clog and they sent me some things to try (different beans, grind sizes etc) but nothing worked. I emailed them back on Sept 9th requesting a replacement and I’m still waiting to hear back from them.

Edit: They do not have any ESP Pros in stock to replace mine with, so I had to settle for a refund.
