Query: What a mess

After having a grind and brew that failed my husband and I decided it was best to go back to a seperate grinder. We found this one and gave it a go. First, the auto-shut off never worked properly. I had to manually shut it off each time I used it. The design of this grinder is terrible. The grounds go into the holder via a small opening in the back, which means that when you remove the container grounds spill onto the counter. The lid removes completely and makes another mess scattering grounds as static has built up along the plastic container. I could not leave this out next to my coffee maker and use it, I had to bring it over to the sink, remove the grounds container, empty it into another container, and then clean the mess up every time. After about 3 weeks, the on/off button stopped working. My husband asked me if I wanted to exchange it for a new one - no way! This design is terrible. I would never purchase again.
