I give 1 star was not because the machine itself, it was the delivery service. I was in my office on my street when the driver arrived, and only took me 10mins from answering the driver's call to returning home. The driver kept going on about the 10min wait and literally yelled at me and pointed fingure at me in the elevator. I shut up in the end because he was really tall and strong and I felt he would punch me if we went on. I have pulled out the camera footage from my building manager and it looked really bad and the building manager suggested me to report to the police as common assult. I am not sure whether the delivery service was hired by Amazon or Endurance, but either way, I demand a solution.
