Good quality materials, plastics that seem good, friendly engine noise hope it will last. A little heavy for a hobby machine, that is the price to pay for wireless. What angry: the basic set of accessories (I already had all that was in it) would have preferred essential accessories like adapter EZ SpeedClic, 4486 Dremel keyless chuck or Dremel 4485 Kit pliers and nut I had to buy extra (cost: 28). Our policy type computer printers ... Despicable and petty.
