This grinder doesn't grind fine enough for espresso machine!
Detailed Commentary
I bought original Solis Maestro 8 years ago and used it daily since. It worked great. Reliable, repeatable. Could easily grind coffee fine enough to jam my Silvia. When It finally gave up on me a few weeks ago, I naturally bought Baratza Maestro Plus. I am very disappointing. Grinder arrived with timer jammed in on position. I figured ok, stuff happens and tried to grind some beans. It doesn't grind nearly fine enough for my silvia!!! I have to return the product and find something else! Very disappointing!
