I made my first healthy smoothly and could not get the lid unscrewed. I don't know why. It took me 5 days to get it open . Then when I tried on the fifth day of came off with no problem. Did I run it to long and pressure built up inside? I don't know. I'm afraid to try again .
No, I would not recommend this to a friend.
