    • Pros
      • Good Scale: Seriously, this thing weighs stuff really.. really well.
      • Water Resistant: For something you'll be putting directly under a water source, this is important.
      • Design!: What's not to love about the dark grey brushed metal and slim black screen inlay?
      • Rechargeable: Convenient, especially if your phone uses the same charging cable!
    • Cons
      • Espresso Size: This is a tiny scale! a little too small to comfortably use for pour overs.
      • Touch Buttons: While better for water resistance, the lack of physical feedback is less than ideal for some.
  • How Does it Compare?
    While possibly the most expensive consumer scale ever made, the Open Box Lunar backs it up with top-of-the-line performance, a well-designed feature set and good looks.
  • Tips and Tricks
    Why Weigh? Espresso is lighter than water! 2 ounces of espresso can weigh as little as 35 grams, while 2 ounces of water weighs around 60 grams. That's half the potential extraction liquid in the same space!
